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

High-quality anatomical structure enhancement for cardiac image dynamic volume rendering | (2008) | Zhang | Publications | SpieHigh-quality anatomical structure enhancement for cardiac image dynamic volume rendering | (2008) | Zhang | Publications | Spie
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 ...

ASTRG AnimationsASTRG Animations
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 ...
CS Colloquium: Deep 3D Representation Learning for Visual Computing | Department of Computer ScienceCS Colloquium: Deep 3D Representation Learning for Visual Computing | Department of Computer Science
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 ...
Image Reconstruction Software Helps Reduce Dose in Nuclear Cardiology | Imaging Technology NewsImage Reconstruction Software Helps Reduce Dose in Nuclear Cardiology | Imaging Technology News

Saddletech Releases The New And Improved Saddletech Gauge MK I I - Equiworld Magazine March 2004Saddletech Releases The New And Improved Saddletech Gauge MK I I - Equiworld Magazine March 2004
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 ...

J. K. Adams, V. Boominathan, B. W. Avants, D. G. Vercosa, F. Ye, R. G. Baraniuk, J. T. Robinson, A. 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 ...
3D/4D Ultrasound3D/4D Ultrasound
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 ...

Use of 3D/4D Ultrasound in the Evaluation of Fetal Anomalies - Tabular View - ClinicalTrials.govUse of 3D/4D Ultrasound in the Evaluation of Fetal Anomalies - Tabular View - ClinicalTrials.gov
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 ...

Effects of Approach Techniques in Place Kicking: A 3D Analysis by Chase M. Pfeifer"Effects of Approach Techniques in Place Kicking: A 3D Analysis" by Chase M. Pfeifer
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 ...

Significant Increase in Image Quality in Widely used 3-D TechniqueSignificant Increase in Image Quality in Widely used 3-D Technique
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 ...

The Differences Between 2D, 3D, and 4D Ultrasounds Explained - Focus on the FamilyThe Differences Between 2D, 3D, and 4D Ultrasounds Explained - Focus on the Family
Ultrasound scans, also known as sonograms, use the reflection of high-frequency sound waves to create images. The standard 2D obstetric ultrasound shows a flat, black and white picture on a screen.. 2D ultrasounds can be done during any trimester, but are often performed early in gestation to confirm the pregnancy and to help establish the due date. This scan is usually repeated at 18-20 weeks of gestation to check for normal growth and development, and to reveal the sex of the baby if desired.. While trained medical professionals have become adept at recognizing features of the developing fetus in 2D, parents are better able to visualize the baby with the advent of 3D ultrasonography.. A 3D ultrasound creates a different perspective by merging a series of 2D images taken from various angles into a composite to form a 3D picture. Because of this increased resolution and visibility, 3D ultrasounds capture a more detailed and realistic representation of the developing baby.. Because 3D ultrasounds ...

neuTube 1.0: A New Design for Efficient Neuron Reconstruction Software Based on the SWC Format | eNeuroneuTube 1.0: A New Design for Efficient Neuron Reconstruction Software Based on the SWC Format | eNeuro
We designed the SWC framework and implemented it in neuTube 1.0 (www.neutracing.com) to improve the efficiency of reconstructing neuron structures accurately. Guided by the framework, the software combines 2D/3D visualization, semi-automated tracing algorithms, and flexible editing options to simplify the task of neuron reconstruction. The SWC framework is not designed to solve the problem of high-throughput neuron tracing, which is different and more challenging. As revealed by the recent DIADEM competition (Liu, 2011), a reliable and generally applicable high-throughput neuron-tracing tool may not be available in the near future. While waiting for the ideal solution, neuroscientists will benefit from better neuron reconstruction tools. Therefore, the goal of the SWC framework is to provide a general architecture, which can adopt state-of-the-art image analysis methods and modern software techniques, for building better interactive neuron reconstruction tools.. Our framework has one limitation, ...

3D computer graphics - Wikipedia3D computer graphics - Wikipedia
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 ...

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 ...

Moving-tolerant Augmented Reality Surgical Navigation System using Autostereoscopic 3D Image Overlay - EMBSMoving-tolerant Augmented Reality Surgical Navigation System using Autostereoscopic 3D Image Overlay - EMBS
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 ...

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 ...

Single-view 3D reconstruction of correlated gamma-neutron sources (Journal Article) | DOE PAGESSingle-view 3D reconstruction of correlated gamma-neutron sources (Journal Article) | DOE PAGES
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 ...

Magnetic Resonance Imaging with Three-Dimensional Analysis of Left Ventricular Remodeling in Isolated Mitral Regurgitation:...Magnetic Resonance Imaging with Three-Dimensional Analysis of Left Ventricular Remodeling in Isolated Mitral Regurgitation:...
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 ...

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). All radiological methods were tested for repeatability and compared with anatomical results for accuracy, and limits of agreement were established. Interchangeability was evaluated by reviewing disparities between the methods and disclosing deterministic differences. Fine intra- ...

Super-resolution of 3D Magnetic Resonance Images by Random Shifting and Convolutional Neural NetworksSuper-resolution of 3D Magnetic Resonance Images by Random Shifting and Convolutional Neural Networks
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 ...

Electrocardiographic gated multislice computed tomography of the thoracic aorta | HeartElectrocardiographic gated multislice computed tomography of the thoracic aorta | Heart
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 ...
Image Guided SurgeryImage Guided Surgery
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 ...

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 ...

Imaging and localizing point sources with high accuracy in a 3D volume is an important but challenging task. For example, super-resolution 3D single molecule localization is an area of intense interest in biology (cell imaging, folding, membrane behavior, etc.), in chemistry (spectral diffusion, molecular distortions, etc.), and in physics (structures of materials, quantum optics, etc.). We consider here the high-resolution imaging problem of 3D point source image recovery from 2D data using methods based on point spread function (PSF) design. The methods involve a new technique, recently patented by S. Prasad, for applying rotating point spread functions with a single lobe to obtain depth from defocus. The amount of rotation of the PSF encodes the depth position of the point source. The distribution of point sources is discretized on a cubical lattice where the indexes of nonzero entries represent the 3D locations of point sources. The values of these entries are the point source fluxes. ...

Management of diffuse low-grade glioma (DLGG) relies extensively on tumour volume estimation from MRI datasets. Two methods are currently clinically used to define this volume: the commonly used three-diameters solution and the more rarely used software-based volume reconstruction from the manual segmentations approach. The authors conducted an initial study of inter-practitioners variability of software-based manual segmentations on DLGGs MRI datasets. A panel of 13 experts from various specialties and years of experience delineated 12 DLGGs MRI scans. A statistical analysis on the segmented tumour volumes and pixels indicated that the individual practitioner, the years of experience and the specialty seem to have no significant impact on the segmentation of DLGGs. This is an interesting result as it had not yet been demonstrated and as it encourages cross-disciplinary collaboration. Their second study was with the three-diameters method, investigating its impact and that of the ...
3D Rotational Angiography of Transplanted Kidneys3D Rotational Angiography of Transplanted Kidneys
Three-dimensional rotational angiography (3D-RA) is an established method within the field of interventional neuroradiology. The method has also a great potential in other areas with a complicated arterial anatomy. The purpose of this study was firstly to develop an investigative protocol for 3D-RA in renal transplanted patients with threatening allograft failure in diagnosing stenosis in the transplanted renal artery; secondly the protocol was evaluated and compared with a modified protocol including reduced contrast medium load. Furthermore, the advantages of the 3D reconstructions compared to the angiographic images were evaluated, likewise if an extended angle of rotation reduced the artifacts in the 3D reconstructions. The two protocols were compared with regard to image quality and acute nephrotoxicity. The accuracy of Doppler ultrasonography and the result of percutaneous transluminal angioplasty (PTA) were also assessed.. 3D-RA was consecutively performed in 57 renal transplanted ...
