A method of computed tomography that uses radionuclides which emit a single photon of a given energy. The camera is rotated 180 or 360 degrees around the patient to capture images at multiple positions along the arc. The computer is then used to reconstruct the transaxial, sagittal, and coronal images from the 3-dimensional distribution of radionuclides in the organ. The advantages of SPECT are that it can be used to observe biochemical and physiological processes as well as size and volume of the organ. The disadvantage is that, unlike positron-emission tomography where the positron-electron annihilation results in the emission of 2 photons at 180 degrees from each other, SPECT requires physical collimation to line up the photons, which results in the loss of many available photons and hence degrades the image.

Structural origins of fibrin clot rheology. (1/8132)

The origins of clot rheological behavior associated with network morphology and factor XIIIa-induced cross-linking were studied in fibrin clots. Network morphology was manipulated by varying the concentrations of fibrinogen, thrombin, and calcium ion, and cross-linking was controlled by a synthetic, active-center inhibitor of FXIIIa. Quantitative measurements of network features (fiber lengths, fiber diameters, and fiber and branching densities) were made by analyzing computerized three-dimensional models constructed from stereo pairs of scanning electron micrographs. Large fiber diameters and lengths were established only when branching was minimal, and increases in fiber length were generally associated with increases in fiber diameter. Junctions at which three fibers joined were the dominant branchpoint type. Viscoelastic properties of the clots were measured with a rheometer and were correlated with structural features of the networks. At constant fibrinogen but varying thrombin and calcium concentrations, maximal rigidities were established in samples (both cross-linked and noncross-linked) which displayed a balance between large fiber sizes and great branching. Clot rigidity was also enhanced by increasing fiber and branchpoint densities at greater fibrinogen concentrations. Network morphology is only minimally altered by the FXIIIa-catalyzed cross-linking reaction, which seems to augment clot rigidity most likely by the stiffening of existing fibers.  (+info)

Three-dimensional facial growth studied by optical surface scanning. (2/8132)

The objective of the investigation was to study the three-dimensional growth of the face, and to examine the hypothesis that there are three-dimensional differences between the faces of boys and girls. The subjects comprised 132 British Caucasians aged 5-10 years measured by optical surface scanning in this cross-sectional study. Average scans for each age and sex subgroup were superimposed to assess the differences with age and sex. Males were generally larger than females. The greatest difference was between the facial heights and the least in the mid-facial dimensions. The face height of both sexes increased by an average of 3-4 mm annually. Mid-face prominence and width altered little. Mandibular width increased by 1-3 mm a year, rising to 3-5 mm in some years at the inferior areas of the mandibular region. Mandibular prominence also increased. Nose height and prominence and alar base width increased by 2 mm per year on average. Dorsum width changed little. Boys were generally larger than girls. Growth in facial height was greatest. Mid-face prominence and width changed little with age, whilst the prominence and width of the lower face increased more. Nasal prominence and alar base width increased at most ages. Dimensions changed more than reported by cephalometric studies, possibly as this study included the soft tissues.

Detection of viable myocardium by dobutamine stress tagging magnetic resonance imaging with three-dimensional analysis by automatic trace method. (3/8132)

The present study attempted to detect the viability of myocardium by quantitative automatic 3-dimensional analysis of the improvement of regional wall motion using an magnetic resonance imaging (MRI) tagging method. Twenty-two subjects with ischemic heart disease who had abnormal wall motion on echocardiography at rest were enrolled. All patients underwent dobutamine stress echocardiography (DSE), coronary arteriography and left ventriculography. The results were compared with those of 7 normal volunteers. MRI studies were done with myocardial tagging using the spatial modulation of magnetization technique. Automatic tracing with an original program was performed, and wall motion was compared before and during dobutamine infusion. The evaluation of myocardial viability with MRI and echocardiography had similar results in 19 (86.4%) of the 22 patients; 20 were studied by positron emission tomography or thallium-201 single photon emission computed tomography for myocardial viability, or studied for improvement of wall motion following coronary intervention. The sensitivity of dobutamine stress MRI (DSMRI) with tagging was 75.9% whereas that of DSE was 65.5%. The specificity of DSMRI was 85.7% (6/7) and that of DSE was 100% (7/7). The accuracy of DSMRI was 77.8% (28/36) and that of DSE 72.2% (26/36). DSMRI was shown to be superior to DSE in terms of evaluation of myocardial viability.  (+info)

Left cervical aortic arch with aortic coarctation and saccular aneurysm. (4/8132)

Cervical aortic arch is a very rare malformation and is occasionally accompanied by other cardiovascular anomalies. A 48-year-old male patient had a left cervical aortic arch with aortic coarctation and saccular aneurysm distal to the coarcted segment. The major clinical manifestations were upper body hypertension with a 50-mmHg discrepancy between the upper and lower limbs and a loud continuous murmur in the upper chest and back. Magnetic resonance angiography successfully depicted the anomalous aorta, and the aortic coarctation and aneurysm were surgically resected and the thoracic aorta was reconstructed. The discrepancy in blood pressure diminished after the operation, but antihypertensive medication was continued to satisfactorily control the hypertension.  (+info)

Three-dimensional ultrasonographic imaging of the neonatal brain in high-risk neonates: preliminary study. (5/8132)

The aim of this investigation was to compare the utility of three-dimensional ultrasonography versus two-dimensional ultrasonography in imaging the neonatal brain. Thirty patients in the neonatal intensive care unit underwent two-dimensional and three-dimensional ultrasonography. The resultant two- and three-dimensional images recorded on film and three-dimensional volumes (reviewed on a workstation) were evaluated independently. Comparable numbers of normal and abnormal studies were diagnosed by each modality. Axial images were considered useful in approximately 50% of three-dimensional cases. Image quality, overall and in the far-field, was rated higher on two-dimensional images. Three-dimensional sonographic acquisition time in the neonatal intensive care unit (1.7 min+/-0.7 standard deviation) was significantly shorter than that for two-dimensional sonography (9.0+/-4.5 min). The total time for evaluation on the three-dimensional workstation (4.4+/-1.1 min) was significantly less than that for two-dimensional images on film (10.6+/-4.7 min). In conclusion, three-dimensional ultrasonography is a promising, diagnostically accurate, and efficient imaging tool for evaluation of the neonatal brain; however, visualization must improve before it can replace two-dimensional ultrasonography.  (+info)

Usefulness of three-dimensional visualization of coronary arteries using electron-beam computed tomography data with volume rendering. (6/8132)

Three-dimensional images of the coronary arteries using electron-beam computed tomography (EBCT) data with shaded surface rendering makes it possible to achieve images easily with a short reconstruction time. However, a lower threshold is required to estimate vessel diameters and there is a quantitative problem compared with conventional coronary arteriography. In combination with volume rendering, EBCT may be useful to detect the normal coronary artery wall, the major components of the atherosclerotic plaque (lipid, fibrous connective tissue and calcium). EBCT scans offer a new, non-invasive alternative to conventional coronary arteriography for diagnosis of coronary artery disease.  (+info)

Clinical application of three-dimensional ultrasound in fetal brain assessment. (8/8132)

AIM: To clarify the usefulness of three-dimensional (3D) ultrasound in the assessment of the fetal head and brain, according to 3D ultrasound surface reconstruction, multiplanar image analysis, three-dimensional angiography, and volume calculation. METHODS: We examined 326 normal fetuses between 10 and 40 weeks of gestation using 3D ultrasound (Voluson, 530D, Medison, Seoul, Korea), mainly with transvaginal 3D transducer. Fetal head structures, such as the skull, brain structure, and brain circulation, were presented by surface mode, multiplanar imaging mode, and three-dimensional Doppler mode. After automatic volume acquisition of the fetal head, image analyses were performed off-line, and 3D View software was used for volume imaging of the lateral ventricle and choroid plexus in randomly selected 30 normal fetuses. Seven fetuses with intracranial abnormalities were evaluated by 3D ultrasound functions. RESULTS: Surface mode of 3D ultrasound objectively depicted in vivo development of the cranial bones and formation of the cranial sutures and fontanelles in normal fetuses. Multiplanar image analysis of the brain structure presented a fetal brain in more cutting sections than conventional 2D ultrasound. Transvaginal 3D angiography was successful in 13% of normal fetuses and rotation of 3D circulatory image allowed the analysis of the intracranial vessels. Volume imaging showed the intracranial structures, such as the lateral ventricle and choroid plexus. Intracranial abnormalities were longitudinally evaluated by 3D ultrasound and objective images helped in reaching prenatal diagnoses. CONCLUSION: Advanced 3D ultrasonography and software for volume analysis can provide additional objective information about the fetal skull formation, brain structure, and brain circulation.  (+info)

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Volume rendering is a technique for visualizing 3D arrays of sampled data. It has applications in areas such as medical imaging and scientific visualization, but its use has been limited by its high computational expense. Early implementations of volume rendering used brute-force techniques that require on the order of 100 seconds to render typical data sets on a workstation. Algorithms with optimizations that exploit coherence in the data have reduced rendering times to the range of ten seconds but are still not fast enough for interactive visualization applications. In this thesis we present a family of volume rendering algorithms that reduces rendering times to one second. First we present a scanline-order volume rendering algorithm that exploits coherence in both the volume data and the image. We show that scanline-order algorithms are fundamentally more efficient than commonly-used ray casting algorithms because the latter

Dynamic volume rendering of the beating heart is an important element in cardiac disease diagnosis and therapy planning, providing the clinician with insight into the internal cardiac structure and functional behavior. Most clinical applications tend to focus upon a particular set of organ structures, and in the case of cardiac imaging, it would be helpful to embed anatomical features into the dynamic volume that are of particular importance to an intervention. A uniform transfer function (TF), such as is generally employed in volume rendering, cannot effectively isolate such structures because of the lack of spatial information and the small intensity differences between adjacent tissues. Explicit segmentation is a powerful way to approach this problem, which usually yields a single binary mask volume (MV), where a unit value in a voxel within the MV acts as a tag label representing the anatomical structure of interest (ASOI). These labels are used to determine the TF employed to adjust the ...

Acoustical data are usually displayed as two-dimensional echograms - vertical dimension through the water column, and time or distance along the horizontal axis. These echograms are used for viewing and evaluating the data. We have developed three-dimensional visualizations of multi-frequency acoustic data to view the data in geographical space from small to large spatial scales (3D Echograms). Acoustic data are commonly used to provide relative indices of species-specific abundance and biomass. In order to scale the relative indices to absolute estimates, we must incorporate a measure of the echo amplitude from an individual fish (3D Modeling). Fish are complicated acoustic scatterers by nature of their complex anatomy and behavior. We have developed three-dimensional visualizations of the fish body and swimbladder from x-ray and Computerized Tomography (CT) images (3D Computerized Tomography). These images are used in theoretical models to improve prediction of acoustic scattering over a ...
Among all digital representations we have for real physical objects, 3D is arguably the most expressive encoding. 3D representations allow storage and manipulation of high-level information (e.g. semantics, affordances, function) as well as low-level features (e.g. appearance, materials) about the object. Exploiting this 3D structure promises to improve our ability to build machines and autonomous agents that sense, understand, and act on the physical world around us. Historically, 3D visual computing has predominantly focused on single 3D models or small model collections. Now, however, with the advent of large 3D repositories of object models and inexpensive 3D scanning, the opportunity arises to re-define the field from the perspective of 3D big data.. In this talk, I will discuss a series of efforts on data-driven 3D visual computing, including constructing an information-rich large-scale 3D model repository (ShapeNet), generating synthetic data for supervising neural networks ...
February 2, 2010 - Two protocols for reduced-dose cardiac imaging, without compromising image quality, may help enhance the performance of gamma cameras by shortening acquisition times, enabling reduced radiopharmaceutical doses and increasing image resolution.. Nuclear medicine image reconstruction software maker UltraSPECT said its imaging protocols minimize radiation exposure to patients and staff, in addition to mitigating the impact of the technetium-99 (Tc-99m ) isotope shortage. The companys FDA-cleared and CE mark-approved Xpress.Cardiac and Xpress3.Cardiac products allow the utilization of lower dose imaging protocols with no compromise in imaging acquisition times and outcomes. UltraSPECT products feature connectivity to the imaging systems of all three major nuclear medicine camera manufacturers, supporting most existing camera hardware and workstation versions. With the Xpress.Cardiac clinicians can apply the one-day rest/stress protocol, with scan times as defined by the ASNC ...
FOR IMMEDIATE RELEASE: WOODSIDE, CA: March 12, 2004: To determine if a saddle FITS a horses back, the laws of geometry require the comparison of all three (3) dimensions, of both surfaces, in relationship to each other. Unfortunately, saddles are not measured in three-dimensions. There is Gullet Width and Seat Length, but there are no standardized three-dimensional measurements to be able to relate the curvature of the horses backs to the shapes of saddles. This lack of an accurate calibrated measurement method is the reason why Equestrians have such difficulty finding a saddle to FIT their horse. To solve this challenge SADDLETECH has just released a new and improved MK I I edition of the CLASSIC SADDLETECH GAUGE that was originally released in 1997. The SADDLETECH GAUGE Mk I I is a simple mechanical instrument that permits the polyform of the shape of horses back and corresponding saddle to be defined by angles and arcs, providing the three-dimensional measurements required to determine ...

When we speak of the dimensions of a quantity, we refer to the type of fundamental quantities that make it up. A dimensional formula shows how a combination of base quantities and their powers represent the dimensions of a physical quantity. Dimensional analysis can be used as a help in working out relationships. According to the principle of homogeneity, the dimensions of each term on both sides of an equation must be the same. Knowledge of dimensions can also be used for conversion between unit systems.

Veeraraghavan, Single-Frame 3D Fluorescence Microscopy with Ultraminiature Lensless FlatScope, Science Advances, Vol. 3, No. 12, 8 December 2017.. Abstract: Modern biology increasingly relies on fluorescence microscopy, which is driving demand for smaller, lighter, and cheaper microscopes. However, traditional microscope architectures suffer from a fundamental trade-off: As lenses become smaller, they must either collect less light or image a smaller field of view. To break this fundamental trade-off between device size and performance, we present a new concept for three-dimensional (3D) fluorescence imaging that replaces lenses with an optimized amplitude mask placed a few hundred micrometers above the sensor and an efficient algorithm that can convert a single frame of captured sensor data into high-resolution 3D images. The result is FlatScope: perhaps the worlds tiniest and lightest ...
WHAT IS A 2D/3D/4D ULTRASOUND?. 2D ultrasound works by listening to sound waves in a single plane. The ultrasound is directed out and reflected back again. An ultrasound is the interpretation of these reflected sound waves to form a visualization of the baby.. In 3D ultrasound, the same ultrasound used in traditional 2D is emitted-this time at multiple angles. 3D ultrasound images are created by an algorithmic process commonly know as surface rendering. These multiple reflections are interpreted through sophisticated software, and an accurate 3D image of the baby is instantly created. These amazing rendered images are displayed with incredible surface detail which delineates both body and facial features.. A 4D ultrasound is captured in the same manner as 3D ultrasound-but the rendering occurs many times per second. Instead of looking at a single still image (3D), you are now able to view real-time video of the baby in the womb (4D). In this case, that 4th Dimension is time.. We offer ...

Conventionally volume measurements can be made by using multiplanar or VOCALTM (Virtual Organ Computer-aided AnaLysis). Recently, a new technique, XI VOCALTM (eXtended Imaging VOCAL) has been described. Combined with the inversion mode, measurements for the liquid-filled structures can also be made. The potential use in clinical diagnosis and prediction of pathologies of volume measurements particularly in the first trimester are yet to be investigated.. 3D ultrasound is found to be superior to 2D parameter in volumetry measurement. However, currently, there are still very few studies done to evaluate the potential use of volumetry measurement in clinical practice, especially of the validity and reproducibility of XI VOCALTM; and the variation of results obtained within different ultrasound machines. Due to the potential use of volumetry measurements in clinical practice, the accuracy in volumetry measurement is very important and the development of new technique need to be fully explored so ...

Various studies aim to understand the fundamentals of kicking, primarily the instep kick commonly used by soccer players. Of those studies, most are limited to a 2D analysis using high-speed cameras for position tracking and electromyography to observe muscle activity. The few studies that investigate a 3D model are limited in their position tracking capabilities and focus mainly on joint flexion potentials and foot speed. To the authors knowledge no study of this caliber has been performed on the kinematics and dynamics of place kicking in American football. This thesis uses a 12 camera high-speed motion tracking system to investigate the kicking techniques of three place kickers of different experience levels by observing several kicks from each. Results demonstrate that the quality of a place kick cannot be determined solely on foot speed but direction and location of foot velocity and the force of the kicking leg at impact. Position and orientation of the plant foot proves to be a driving factor in

3D ultrasound imaging is quickly gaining widespread clinical acceptance as a visualization tool that allows clinicians to obtain unique views not available with traditional 2D ultrasound imaging and an accurate understanding of patient anatomy. The ability to acquire, manipulate and interact with the 3D data in real time is an important feature of 3D ultrasound imaging. Volume rendering is often used to transform the 3D volume into 2D images for visualization. Unlike computed tomography (CT) and magnetic resonance imaging (MRI), volume rendering of 3D ultrasound data creates noisy images in which surfaces cannot be readily discerned due to speckles and low signal-to-noise ratio. The degrading effect of speckles is especially severe when gradient shading is performed to add depth cues to the image. Several researchers have reported that smoothing the pre-rendered volume with a 3D convolution kernel, such as 5x5x5, can significantly improve the image quality, but at the cost of decreased ...

OBJECTIVES: To develop and evaluate a fully automatic method to measure diameters of the ascending and descending aorta on non-ECG-gated, non-contrast computed tomography (CT) scans.. MATERIAL AND METHODS: The method combines multi-atlas registration to obtain seed points, aorta centerline extraction, and an optimal surface segmentation approach to extract the aorta surface around the centerline. From the extracted 3D aorta segmentation, the diameter of the ascending and descending aorta was calculated at cross-sectional slices perpendicular to the extracted centerline, at the level of the pulmonary artery bifurcation, and at 1-cm intervals up to 3 cm above and below this level. Agreement with manual annotations was evaluated by dice similarity coefficient (DSC) for segmentation overlap, mean surface distance (MSD), and intra-class correlation (ICC) of diameters on 100 CT scans from a lung cancer screening trial. Repeatability of the diameter measurements was evaluated on 617 baseline-one year ...

The rendering organization industry is included such endless branches, the commonest of which is cloud rendering. Under cloud rendering, PC mists are outlined to convey accounts of astoundingly significant standard. This kind of rendering is incredibly typical since it is sensible and makes extraordinary quality chronicles. With cloud rendering, all parts of the video delivered is changed over into significant standard, thus, making the whole video extremely comprehended. All things considered, with cloud rendering, all parts of the video gets observable. Essential for note is that cloud rendering is for the most part used for chronicles that need significant standard, or those that ought to be incredibly clear to interest customers, for example PC games. An observable PC game is absolutely more captivating than a game that is not clear. 3D rendering can be described as rendering that produces cloud like substances in the background of chronicles and plans. It is the kind of rendering that gives ...

Anaglyph printing - think of the red-and-blue 3D glasses used to transform 2D images to 3D images in comics, magazines, books, and newspapers - came into being when the continuous-tone printed anaglyph was invented by French physicist Louis Ducos du Hauron in 1891.. The technique works by combining the left and right images of a stereoscopic image pair into the red and blue color channels of the output anaglyph image. With the red/blue 3D glasses, the left eye sees only the red channel of the anaglyph image, and the right sees only sees the blue. If the anaglyph 3D image has been constructed correctly, the viewer sees a pleasing 3D image on the printed page.. The project team, led by Curtin research engineer Andrew Woods, targeted crosstalk problems which are visible as ghost-like shadows. Their paper published recently in the SPIE journal Optical Engineering details seven recommendations for overcoming crosstalk.. The largest reduction in crosstalk is likely be achieved by using inks which ...

3D computer graphics or three-dimensional computer graphics (in contrast to 2D computer graphics), are graphics that use a three-dimensional representation of geometric data (often Cartesian) that is stored in the computer for the purposes of performing calculations and rendering 2D images. Such images may be stored for viewing later or displayed in real-time. 3D computer graphics rely on many of the same algorithms as 2D computer vector graphics in the wire-frame model and 2D computer raster graphics in the final rendered display. In computer graphics software, 2D applications may use 3D techniques to achieve effects such as lighting, and 3D may use 2D rendering techniques. 3D computer graphics are often referred to as 3D models. Apart from the rendered graphic, the model is contained within the graphical data file. However, there are differences: a 3D model is the mathematical representation of any three-dimensional object. A model is not technically a graphic until it is displayed. A model ...

VAL, Aurore et al. 3D techniques and fossil identification: an elephant shrew hemi-mandible from the Malapa site. S. Afr. j. sci. [online]. 2011, vol.107, n.11-12, pp.01-05. ISSN 1996-7489.. Conventional methods for extracting fossilised bones from calcified clastic sediments, using air drills or chemical preparations, can damage specimens to the point of rendering them unidentifiable. As an alternative, we tested an in silico approach that extended preparation and identification possibilities beyond those realisable using physical methods, ultimately proving to be crucial in identifying a fragile fossil. Image data from a matrix-encased hemi-mandible of a micromammal that was collected from the Plio-Pleistocene site of Malapa, Cradle of Humankind, South Africa, were acquired using microtomography. From the resultant images, a 3D rendering of the fossil was digitally segmented. Diagnostic morphologies were evaluated on the rendering for comparison with extant comparative specimens, positively ...

This paper proposes a statistical multiscale homogenization method to extract effective elastic properties of cement paste on the basis of X-ray microtomography images. The procedure starts at the nanolevel of the C-S-H matrix. Because the highest resolution of current X-ray microtomography is at micrometer scale, C-S-H and CH remains unsegmented. The unresolved hydrated cement is homogenized by a two-step analytical method based on Mori-Tanaka (M-T) scheme. A statistical numerical homogenization method based on the Finite Element Method (FEM) was used to homogenize the elastic properties of cement pastes. Mean elastic properties showed good agreement with experimental results. The proposed multiscale method combines advanced analytical, numerical and experimental methods in a systematical way so that the inputs are phase material properties and X-ray microtomography images only. The novelty of this method is in the avoidance of any subjective decision ...
Purpose.: To investigate the optical intensities of all retinal layers on three-dimensional (3D) spectral-domain optical coherence tomography (SD-OCT) in normal subjects using an automatic measurement. Methods.: Forty normal subjects underwent Topcon 3D OCT-1000 macula-centered scan. The raw data were automatically segmented into 10 layers using the 3D graph search approach. Then the mean and standard deviation of intensities of each layer were calculated. The image quality index was given by the OCT software. Correlation analysis was performed between the optical intensities in each layer and image quality and subjects age. Results.: The correlation of optical intensities was strong from ganglion cell layer (GCL) to outer nuclear layer (ONL) with r , 0.934; moderate among retinal nerve fiber layer (RNFL), photoreceptor, retinal pigment epithelium (RPE), and choroid (0.410 , r , 0.800); and low in the vitreous (0.251 , r , 0.541). The optical intensities were also correlated with the image ...
With the development of precise three-dimensional motion measurement systems and powerful computers for three-dimensional graphical visualization, it is possible to record and fully reconstruct human jaw motion. In this paper, we describe a visualization system for displaying three-dimensional jaw movements in speech. The system is designed to take as input jaw motion data obtained from one or multi-dimensional recording systems. In the present application, kinematic records of jaw motion were recorded using an optoelectronic measurement system (Optotrak). The corresponding speech signal was recorded using an analog input channel. The three orientation angles and three positions that describe the motion of the jaw as a rigid skeletal structure were derived from the empirical measurements. These six kinematic variables, which in mechanical terms account fully for jaw motion kinematics, act as inputs that drive a real-time three-dimensional animation of a skeletal jaw and upper skull. The ...
We consider diffusion in arbitrary spatial dimension d with the addition of a resetting process wherein the diffusive particle stochastically resets to a fixed position at a constant rate $r$. We compute the non-equilibrium stationary state which exhibits non-Gaussian behaviour. We then consider the presence of an absorbing target centred at the origin and compute the survival probability and mean time to absorption of the diffusive particle by the target. The mean absorption time is finite and has a minimum value at an optimal resetting rate $r^*$ which depends on dimension. Finally we consider the problem of a finite density of diffusive particles, each resetting to its own initial position. While the typical survival probability of the target at the origin decays exponentially with time regardless of spatial dimension, the average survival probability decays asymptotically as $\exp -A (\log t)^d$ where $A$ is a constant. We explain these findings using an interpretation as a renewal process ...

Augmented reality (AR) surgical navigation systems based on image overlay have been used in minimally invasive surgery (MIS). However, conventional systems still suffer from a limited viewing zone, a shortage of intuitive three-dimensional (3D) image guidance and cant be moved freely. To fuse the 3D overlay image with the patient in situ, it is essential to track the overlay device while it is moving. A direct line-of-sight should be maintained between the optical markers and the tracker camera. We propose a moving-tolerant AR surgical navigation system using autostereoscopic image overlay, which can avoid the use of the optical tracking system during the intraoperative period. The system captures binocular image sequences of environmental change in the operation room to locate the overlay device, rather than tracking the overlay device directly. Therefore, it is no longer required to maintain a direct line-of-sight between the tracker and the tracked devices. The movable range of the system is ...
Objective: A qualitative study was conducted to explore dimensions underlying psychosocial barriers to prevention of early childhood caries among recent immigrants in Edmonton, Canada. Method: Eleven focus groups were completed with 65 mothers of 3-5 year old children from African and South Asian communities. Participants had lived in Canada for five years or less. Four debriefing interviews were conducted with the community workers who facilitated the focus groups in participants first languages. A dimensional analysis was used for data analysis. Result: Type, level, nature, awareness, controllability, influence, objectiveness, and interdependence were the most salient dimensions underlying barriers to home-based and professional-based preventions. Type refers to a barrier itself while level refers to where the barrier was located (individual, family, community, or systemic level). Nature expresses the inherent character of identified barriers which were related to knowledge, skills, ...

The following thesis presents a protocol for the three-dimensional visualization of the cranial nerves V-VIII within the basal cisterns, being optimized with regard to data acquisition and postprocessing. Based on high resolution MRI datasets and using the volume rendering technique, 10 standardized views of the aforementioned cranial nerves were developed. Thus, the complete and time effective intracisternal depiction was intended to be made possible, focussing on pathophysiological important areas of the nerves. The protocol showed its suitability concerning image quality and diagnostic value in evaluation of patients with neurovascular conflicts or other neural compression syndromes in the cerebello-pontine angle. Problems mainly occurred as a result of pulsation and motion artefacts in the MR dataset and narrow cisterns in the level of the virtual camera position. In most cases they could be solved by slight variations of the postprocessing parameters. To guaranty the correct identification ...

We describe a new method of 3D image reconstruction of neutron sources that emit correlated gammas (e.g. Cf- 252, Am-Be). This category includes a vast majority of neutron sources important in nuclear threat search, safeguards and non-proliferation. Rather than requiring multiple views of the source this technique relies on the sources intrinsic property of coincidence gamma and neutron emission. As a result only a single-view measurement of the source is required to perform the 3D reconstruction. In principle, any scatter camera sensitive to gammas and neutrons with adequate timing and interaction location resolution can perform this reconstruction. Using a neutron double scatter technique, we can calculate a conical surface of possible source locations. By including the time to a correlated gamma we further constrain the source location in three-dimensions by solving for the source-to-detector distance along the surface of said cone. As a proof of concept we applied these reconstruction ...

Background-Although surgery is indicated in patients with mitral regurgitation (MR) when left ventricular (LV) end-systolic (ES) dimension (D) is ,40mm, LV ejection fraction (EF) may decrease post-mitral valve surgery. We hypothesize that significant LV remodeling pre-surgery is not reflected by standard echocardiographic parameters measured at the base of the heart. Methods and Results-94 patients (54±11 years, 38% female) with degenerative isolated MR underwent cine-magnetic resonance imaging (MRI) with tissue tagging and three-dimensional analysis. In 51 control subjects (44±14 years, 53% female), the relation between LVES volume (V) and LVESD was quadratic, while in 94 MR patients this relation was cubic, indicating greater increase in LVESV per LVESD amongst MR patients. Moreover, MRI LVESV from summated serial short axis slices was significantly greater than LVESV using the Bullet formula in MR patients, attributed to a more spherical remodeling distal to the tips of the papillary ...
To train, evaluate, and validate the application of a deep learning framework in three-dimensional ultrasound (3D US) for the automatic segmentation of ventricular volume in preterm infants with post haemorrhagic ventricular dilatation (PHVD). We trained a 2D convolutional neural network (CNN) for automatic segmentation ventricular volume from 3D US of preterm infants with PHVD. The method was validated with the Dice similarity coefficient (DSC) and the intra-class coefficient (ICC) compared to manual segmentation. The mean birth weight of the included patients was 1233.1 g (SD 309.4) and mean gestational age was 28.1 weeks (SD 1.6). A total of 152 serial 3D US from 10 preterm infants with PHVD were analysed. 230 ventricles were manually segmented. Of these, 108 were used for training a 2D CNN and 122 for validating the methodology for automatic segmentation. The global agreement for manual versus automated measures in the validation data (n=122) was excellent with an ICC of 0.944 (0.874-0.971). ...
With the current widespread use of 3D facial surface imaging in clinical and research environments, there is a growing demand for high quality craniofacial norms based on 3D imaging technology. The principal goal of the 3D Facial Norms (3DFN) project was to create an interactive, web-based repository of 3D facial images and measurements. Unlike other repositories, users can gain access to both summary-level statistics as well as individual-level data, including 3D facial landmark coordinates, 3D-derived anthropometric measurements, 3D facial surface images and genotypes from every individual in the dataset. The 3DFN database currently consists of 2454 male and female participants ranging in age from 3-40 years. These subjects were recruited at four US sites and screened for a history of craniofacial conditions. The goal of this paper is to introduce readers to the 3DFN repository by providing a general overview of the project, explaining the rationale behind the creation of the database, and ...
The observations presented in this paper collectively indicate that high-frequency three-dimensional power Doppler ultrasound can be used to assess functional neoangiogenesis in GEM prostate cancer models. The power Doppler signal is proportional to the concentration of blood cells flowing at velocities high enough to be detected by the Doppler system (e.g., , 3 mm/s in this study). The CPD is therefore considered an estimate of the fraction of the tissue volume that is occupied by moving blood ( 23). Tumor CPD data reflect flow in intermediate-sized (e.g., ,100 μm diameter) arterioles and venules and arteriovenous shunts. Vessels imaged by power Doppler are functional in the sense that they support active blood flow. This point is an important aspect of interpreting Doppler images of tumors because as few as 20% of the vessels in a tumor may be perfused at any given instant, and tumor perfusion varies both spatially and temporally ( 19). In addition, unlike many other imaging techniques, ...

This study evaluated the potential impact of different visualisation methods of cone-beam computed tomography (CBCT) on the accuracy of linear measurements of calcified structures, and assessed their interchangeability. High resolution (0.125 mm voxel) CBCT scans were obtained from eight cadaveric heads. The distance between the alveolar bone ridge and the incisal edge was determined for all mandibular incisors and canines, both anatomically and with measurements based on the following five CBCT visualisation methods: isosurface, direct volume rendering, multiplanar reformatting (MPR), maximum intensity projection of the volume of interest (VOIMIP), and average intensity projection of the volume of interest (VOIAvIP).

Enhancing resolution is a permanent goal in magnetic resonance (MR) imaging, in order to keep improving diagnostic capability and registration methods. Super-resolution (SR) techniques are applied at the postprocessing stage, and their use and development have progressively increased during the last years. In particular, example-based methods have been mostly proposed in recent state-of-the-art works. In this paper, a combination of a deep-learning SR system and a random shifting technique to improve the quality of MR images is proposed, implemented and tested. The model was compared to four competitors: cubic spline interpolation, non-local means upsampling, low-rank total variation and a three-dimensional convolutional neural network trained with patches of HR brain images (SRCNN3D). The newly proposed method showed better results in Peak Signal-to-Noise Ratio, Structural Similarity index, and Bhattacharyya coefficient. Computation times were at the same level as those of these up-to-date ...

A 72 year old man attended for follow up computed tomography (CT) of a chronic type A aortic dissection, three years on from his original presentation. The contrast enhanced multislice CT was acquired using retrospective ECG gating. Subsequent reconstruction of the CT images was from a diastolic reconstruction window centred at 75% of the RR interval. This mode of acquisition provided images of the thoracic aorta free of motion artefact. The chronic dissection flap could clearly be seen arising in the proximal, aneurysmal ascending aorta (panel A, axial CT section), extending to the head and neck vessels (panel B, sagittal CT section), and progressing distally to the descending aorta (panel C, three dimensional reconstruction in sagittal section). Advanced post-processing using volume rendering techniques demonstrated the dissection (panel C) and the aneurysm (panel D) in three dimension.. Aortic motion artefact is the most common cause of false positive detection of dissection of the ...
The segmentation is performed using automated techniques and semi-automated techniques. Automatic segmentation techniques include an automatic gain artifact suppression technique based on expectation-maximization in association with a cortical volume isolation technique based on image morphology and active contours. Below is a slice of an MRI, with the brain, ventricles, and tumor segmented. We use surface rendering techniques to display the segmented MRI structures. This procedure consists of first extracting bounding surfaces from the segmented MRI volume using the marching cubes algorithm. This algorithm generates a set of connected triangles to represent the 3D surface for each segmented structure. These surfaces are then displayed by selecting a virtual viewing camera location and orientation in the MRI coordinate frame and using standard computer graphics techniques to project the surface onto the viewing camera. This rendering process removes hidden portions of the surface, shades the ...
A new three-dimensional (3D) MR imaging pulse sequence can produce over 100 high-resolution, high-contrast images in as little as 6 minutes of imaging time. Without additional imaging time, this same image data can be post-processed to yield high-resolution, high-contrast images in any arbitrary orientation. Thus, this new pulse sequence technique provides detailed yet comprehensive coverage. The method of this invention relates to a preparation-acquisition-recovery sequence cycle. The first step is magnetization preparation (MP) period. The MP period can emply a series of RF pulses, gradient field pulses, and/or time delays to encode the desired contrast properties in the form of longitudinal magnetization. A data acquisition period includes at least two repetitions of a gradient echo sequence to acquire data for a fraction of k-space. A magnetization recovery period is provided which allows T1 and T2 relaxation before the start of the next sequence cycle. The MP, data acquisition and magnetization
This invention is a system for use during a medical or surgical procedure on a body. The system generates an image representing the position of one or more body elements (10, 20, 30) using scans generated by a scanner prior or during the procedure. The image data set has reference points (10A)-(30C) for each of the body elements, the reference points of a body element having a fixed spatial relation to the body element. The system includes an apparatus (108) for identifying the relative position of each of the reference points of each of the body elements to be displayed. The system also includes a processor (104) for modifying the image data set according to the identified relative position of each of the reference points during the procedure. Also disclosed are devices for use with a surgical navigation system having a sensor array (110, 112) in communication with the device to identify its position.
Kyle Tallakson, Colorado State University Mechanical Engineering major, is building a 3D printed spinal fusion in the Idea2Product lab for his Advance Additive Manufacturing Engineering, MECH 502. The original project was to create a spinal fusion model. We took a CT scan (Computerized Tomography scan) and made it into a 3D model, Tallakson said. Tallakson is working on the project with a team. I got the CT scan from the hospital after an accident I had a couple years ago, Tallakson said. Tallakson was hit by a car going down Elizabeth Street in Fort Collins, CO and split his kidney in half. They threw me in a CT scan just to see if I was bleeding internally or if I had any other broken bones. Luckily Tallakson had no other broken bones from the accident. Tallakson was able to request the CT Scan for free from the hospital and then used 3D Slicer, an open source software platform for medical image informatics, image processing, and three-dimensional visualization, to separate each vertebra ...
