Differentiation of small hyperechoic renal cell carcinoma from angiomyolipoma: computer-aided tissue echo quantification. (1/6032)

To assess the value of computer-aided tissue echo quantification in differentiating small hyperechoic renal cell carcinomas from angiomyolipomas, we studied ultrasonographic images of 15 renal cell carcinomas and 20 angiomyolipomas. After digitizing the images, we measured the absolute gray scale values of the renal cortex, central echo complex, and mass. The relative gray scale value (%) of the mass was calculated by setting the gray scale value of the cortex as 0% and the central echo complex as 100%. The relative gray scale value of renal cell carcinomas was in the range of 12 to 73% (mean, 28%), whereas that of angiomyolipomas was 30 to 204% (mean, 130%). The differentiation between small hyperechoic renal cell carcinomas and angiomyolipomas can be facilitated by computer-aided tissue echo quantification.  (+info)

Inter- and intraobserver variation in the analysis of optic disc images: comparison of the Heidelberg retina tomograph and computer assisted planimetry. (2/6032)

AIMS: The development of imaging and measurement techniques has brought the prospect of greater objectivity in the measurement of optic disc features, and therefore better agreement between observers. The purpose of this study was to quantify and compare the variation between observers using two measurement devices. METHODS: Optic disc photographs and images from the Heidelberg retina tomograph (HRT) of 30 eyes of 30 subjects were presented to six observers for analysis, and to one observer on five separate occasions. Agreement between observers was studied by comparing the analysis of each observer with the median result of the other five, and expressed as the mean difference and standard deviation of differences between the observer and the median. Inter- and intraobserver variation was calculated as a coefficient of variation (mean SD/mean x 100). RESULTS: For planimetry, agreement between observers was dependent on observer experience, for the HRT it was independent. Agreement between observers (SD of differences as a percentage of the median) for optic disc area was 4.0% to 7.2% (planimetry) and 3.3% to 6.0% (HRT), for neuroretinal rim area it was 10.8% to 21.0% (planimetry) and 5.2% to 9.6% (HRT). The mean interobserver coefficient of variation for optic disc area was 8.1% (planimetry) and 4.4% (HRT), for neuroretinal rim area it was 16.3% (planimetry) and 8.1% (HRT), and (HRT only) for rim volume was 16.3%, and reference height 9.1%. HRT variability was greater for the software version 1.11 reference plane than for version 1.10. The intraobserver coefficient of variation for optic disc area was 1.5% (planimetry) and 2.4% (HRT), for neuroretinal rim area it was 4.0% (planimetry) and 4.5% (HRT). CONCLUSIONS: Variation between observers is greatly reduced by the HRT when compared with planimetry. However, levels of variation, which may be clinically significant, remain for variables that depend on the subjective drawing of the disc margin.  (+info)

Effect of software manipulation (Photoshop) of digitised retinal images on the grading of diabetic retinopathy. (3/6032)

AIMS: To determine whether software processing of digitised retinal images using a "sharpen" filter improves the ability to grade diabetic retinopathy. METHODS: 150 macula centred retinal images were taken as 35 mm colour transparencies representing a spectrum of diabetic retinopathy, digitised, and graded in random order before and after the application of a sharpen filter (Adobe Photoshop). Digital enhancement of contrast and brightness was performed and a X2 digital zoom was utilised. The grades from the unenhanced and enhanced digitised images were compared with the same retinal fields viewed as slides. RESULTS: Overall agreement in retinopathy grade from the digitised images improved from 83.3% (125/150) to 94.0% (141/150) with sight threatening diabetic retinopathy (STDR) correctly identified in 95.5% (84/88) and 98.9% (87/88) of cases when using unenhanced and enhanced images respectively. In total, five images were overgraded and four undergraded from the enhanced images compared with 17 and eight images respectively when using unenhanced images. CONCLUSION: This study demonstrates that the already good agreement in grading performance can be further improved by software manipulation or processing of digitised retinal images.  (+info)

Vascular endothelial cells respond to spatial gradients in fluid shear stress by enhanced activation of transcription factors. (4/6032)

The vascular endothelium is exposed to a spectrum of fluid mechanical forces generated by blood flow; some of these, such as fluid shear stress, can directly modulate endothelial gene expression. Previous work by others and in our laboratory, using an in vitro uniform laminar shear stress model, has identified various shear stress response elements (SSREs) within the promoters of certain endothelial genes that regulate their expression by interacting with various transcription factors, including nuclear factor-kappaB (NF-kappaB), early growth response-1 (Egr-1), and activator protein-1 (AP-1, composed of c-Jun/c-Jun and c-Jun/c-Fos protein dimers). In the current study, we have examined the topographical patterns of NF-kappaB, Egr-1, c-Jun, and c-Fos activation in a specially designed in vitro disturbed laminar shear stress model, which incorporates regions of significant spatial shear stress gradients similar to those found in atherosclerosis-prone arterial geometries in vivo (eg, arterial bifurcations, curvatures, ostial openings). Using newly developed quantitative image analysis techniques, we demonstrate that endothelial cells subjected to disturbed laminar shear stress exhibit increased levels of nuclear localized NF-kappaB, Egr-1, c-Jun, and c-Fos, compared with cells exposed to uniform laminar shear stress or maintained under static conditions. In addition, individual cells display a heterogeneity in responsiveness to disturbed flow, as measured by the amount of NF-kappaB, Egr-1, c-Jun, and c-Fos in their nuclei. This differential regulation of transcription factor expression by disturbed versus uniform laminar shear stress indicates that regional differences in blood flow patterns in vivo-in particular, the occurrence of spatial shear stress gradients-may represent important local modulators of endothelial gene expression at anatomic sites predisposed for atherosclerotic development.  (+info)

Fully automated microvessel counting and hot spot selection by image processing of whole tumour sections in invasive breast cancer. (5/6032)

BACKGROUND: Manual counting of microvessels is subjective and may lead to unacceptable interobserver variability, which may explain conflicting results. AIMS: To develop and test an automated method for microvessel counting and objective selection of the hot spot, based on image processing of whole sections, and to compare this with manual selection of a hot spot and counting of microvessels. METHODS: Microvessels were stained by CD31 immunohistochemistry in 10 cases of invasive breast cancer. The number of microvessels was counted manually in a subjectively selected hot spot, and also in the same complete tumour sections by interactive and automated image processing methods. An algorithm identified the hot spots from microvessel maps of the whole tumour section. RESULTS: No significant difference in manual microvessel counts was found between two observers within the same hot spot, and counts were significantly correlated. However, when the hot spot was reselected, significantly different results were found between repeated counts by the same observer. Counting all microvessels manually within the entire tumour section resulted in significantly different hot spots than manual counts in selected hot spots by the same observer. Within the entire tumour section no significant differences were found between the hot spots of the manual and automated methods using an automated microscope. The hot spot was found using an eight connective path search algorithm, was located at or near the border of the tumour, and (depending on the size of the hot spot) did not always contain the field with the largest number of microvessels. CONCLUSIONS: The automated counting of microvessels is preferable to the manual method because of the reduction in measurement time when the complete tumour is scanned, the greater accuracy and objectivity of hot spot selection, and the possibility of visual inspection and relocation of each measurement field afterwards.  (+info)

Abnormal cerebral structure in juvenile myoclonic epilepsy demonstrated with voxel-based analysis of MRI. (6/6032)

MRI scans of patients with idiopathic generalized epilepsy (IGE) are normal on visual assessment. Using an interactive anatomical segmentation technique and volume-of-interest measurements of MRI, we showed recently that patients with IGE had significantly larger cortical grey matter than control subjects. Further, 40% of individual patients with juvenile myoclonic epilepsy (JME), a syndrome of IGE in adolescence, had significant abnormalities of cerebral structure. In this study, we applied the automated and objective technique of statistical parametric mapping (SPM) to the analysis of structural MRI from 20 patients with JME and 30 control subjects. The cortical grey matter of each individual JME patient and the group of JME patients was contrasted with that of the group of 30 normal subjects. The voxel-based SPM comparison between the group of JME patients and the control subjects showed an increase in cortical grey matter in the mesial frontal lobes of the patients. Analysis of individual patients revealed significant abnormalities of cortical grey matter in five out of 20 JME patients, four of whom had been shown to have widespread abnormalities using the previous volume of interest technique. These findings indicate a structural cerebral abnormality in JME, with involvement of mesiofrontal cortical structures.  (+info)

Cranionavigator combining a high-speed drill and a navigation system for skull base surgery--technical note. (7/6032)

Drilling of the skull base bone without damaging the important inside structures and with the correct orientation is very difficult even with the help of the anatomical landmarks. Monitoring of the location and direction of the drill tip and indications of the removed part of the bone during the drilling procedure enhances safety and achieves less invasive neurosurgery. We have developed a novel cranionavigator by combining a high-speed drill with a neurosurgical navigation system. To reduce the positional error to less than 1.5 mm, the position sensor (magnetic field sensor) must be attached 5 cm from the metallic fan portion of the drill and the sensor kept at least 10 cm away from the operating microscope. Simulation studies with the cranionavigator using two dried skulls and three cadaver heads were performed before clinical application. Clinically, this surgical instrument was used in four patients with the skull base tumor. The cranionavigator helped to safely drill the skull base bone in a shorter time by dynamic and real-time display of the precise operating site and extent of bone drilling on the preoperative computed tomography scans or magnetic resonance images. The cranionavigator is a very helpful instrument for skull base surgery in the hands of neurosurgeons with extensive expertise and anatomical knowledge.  (+info)

Angiogenesis in neuroblastoma: relationship to survival and other prognostic factors in a cohort of neuroblastoma patients. (8/6032)

PURPOSE: To study angiogenesis in neuroblastoma, using morphometric and computerized image analysis, and correlate the results with survival and other prognostic factors. PATIENTS AND METHODS: Sixty-nine patients from the Spanish Cooperative Study for Neuroblastoma were studied. Tumoral angiogenesis was studied using an avidin-biotin immunoperoxidase technique with an anti-CD34 antibody. Vascular parameters (VPs) were analyzed by a computerized system. Statistical analysis was also performed. RESULTS: Sixty-six samples had adequate tumoral tissue, and their tumoral vessels were counted. Endothelial cells were more prominent in pure neuroblastomas than in maturing and more mature tumors. VPs showed no statistical difference between the groups of patients as defined by the levels of the other prognostic factors in neuroblastoma: age, stage, histopathology, TRK-A, P-glycoprotein expression, or MYCN copy number. In patients who relapsed, tumors did not show statistically significant difference in VPs when compared with tumors from patients who did not relapse. There was also no difference in VPs in tumors from living patients when compared with tumors from deceased patients. Overall survival was 75%, and event-free survival was 55% at 50 months. CONCLUSION: VPs could be adequately determined by a computerized system in neuroblastoma; however, VPs were not predictive of survival for our patients. In our patients, neither disseminated nor local relapses were influenced by the angiogenic characteristics of the tumors.  (+info)

PURPOSE: As Quantitative Susceptibility Mapping (QSM) is maturing, more clinical applications are being explored. With this comes the question whether QSM is sufficiently robust and reproducible to be directly used in a clinical setting where patients are possibly not cooperative and/or unable to suppress involuntary movements sufficiently. Subjects and Methods: Twenty-nine patients with Alzheimers Disease (AD), 31 patients with Mild Cognitive Impairment (MCI) and 41 healthy controls (HC) were scanned on a 3T scanner, including a multi-echo gradient-echo sequence for QSM and an inversion-prepared segmented gradient-echo sequence (T1-TFE, MPRAGE). The severity of motion artifacts (excessive/strong /noticeable/invisible) was categorized via visual inspection by two independent raters. Quantitative susceptibility was reconstructed using Joint background-field removal and segmentation-Enhanced Dipole Inversion (JEDI), based on segmented subcortical gray-matter regions, as well as using ...

Previous studies have detected abnormal serum ferritin levels in patients with depression; however, the results have been inconsistent. This study used quantitative susceptibility mapping (QSM) for the first time to examine brain iron concentration in depressed patients and evaluated whether it is related to severity. We included three groups of age- and gender-matched participants: 30 patients with mild-moderate depression (MD), 14 patients with major depression (MDD) and 20 control subjects. All participants underwent MR scans with a 3D gradient-echo sequence reconstructing for QSM and performed the 17-item Hamilton Depression Rating Scale (HDRS) test. In MDD, the susceptibility value in the bilateral putamen was significantly increased compared with MD or control subjects. In addition, a significant difference was also observed in the left thalamus in MDD patients compared with controls. However, the susceptibility values did not differ between MD patients and controls. The susceptibility values

AU - Shen, Dinggang. PY - 2020/1/1. Y1 - 2020/1/1. N2 - Automatic image segmentation is an essential step for many medical image analysis applications, include computer-aided radiation therapy, disease diagnosis, and treatment effect evaluation. One of the major challenges for this task is the blurry nature of medical images (e.g., CT, MR, and microscopic images), which can often result in low-contrast and vanishing boundaries. With the recent advances in convolutional neural networks, vast improvements have been made for image segmentation, mainly based on the skip-connection-linked encoder-decoder deep architectures. However, in many applications (with adjacent targets in blurry images), these models often fail to accurately locate complex boundaries and properly segment tiny isolated parts. In this ...
Lesions displaying peripheral rings in the phase images were identified in 10 of the 39 subjects. Dipolar projections were apparent in the phase images outside of the extent of several of these lesions; however, QSM images showed peripheral rings without such projections. These projections appeared ring-like in a small number of phase images where no ring was observed in QSM. 1D profiles of six well-isolated example lesions showed that QSM contrast corresponds more closely to the magnitude images than phase contrast ...

GENERATING AN EROSION IMAGE UTILIZING PARALLEL PIXEL PROCESSING - An erosion image is generated from an original digital image utilizing a processing image (b) and a target image (T), where each pixel in the target image is processed in parallel. The process entails, for each target pixel, i) determining coordinate values for the target pixel, ii) determining a surrounding pixel area for the target pixel, iii) and processing each pixel in the surrounding pixel area to determine whether or not to updated the value of the target pixel. In processing each surrounding pixel, a determination is made whether the pixel has a value of 1. If not, then the next surrounding pixel is processed. If so, then a determination is made which pixel element of a structuring element overlays the target pixel, and whether that SE pixel has a value of 1. If so, then the value of the target pixel is updated. If not, then the next pixel in the surrounding pixel area is processed. Once the target pixel has been updated a ...
Hough states that Lasorda did a great job convincing Eddie Robinson, the Texas General Manager, to acquire him with the way he was performing. [16] Late in the year, the 32-year-old Hough made just the 16th start of his career, when Ferguson Jenkins was arrested for cocaine possession. Charlie pitched a five-hit shutout on August 26th (All I could think about was, keep Fergie in jail. Lock him up and throw away the key) but did not get to pitch again for 17 days. He stated later that he said it was a good thing I didnt throw a no-hitter. I might never have pitched again. [17] He was 2-2 with a 3.96 ERA for the 1980 Rangers, beginning to right the course of his career. In 1981, Hough was 4-1 with a save and a 2.96 ERA in a good year cut short by the 1981 strike. The next year, 1982, he became a regular member of the starting rotation and went 16-13 with a 3.95 ERA, tying Dennis Martinez and Jim Clancy for 8th in the 1982 AL in victories and Ken Forsch, Geoff Zahn and Mike Caldwell for fifth ...

PURPOSE: The aim of this project was to establish a database of left and right ventricular and left atrial dimensions in healthy volunteers using steady-state free precession cardiac magnetic resonance imaging, the clinical technique of choice, across a wide age range. METHODS: 108 healthy volunteers (63 male, 45 female) underwent cardiac magnetic resonance imaging using steady-state free precession sequences. Manual analysis was performed by 2 experienced observers. RESULTS: Left and right ventricular volumes and left ventricular mass were larger in males than females: LV end-diastolic volume 160 +/- 29 mL vs. 135 +/- 26 mL, LV end-systolic volume 50 +/- 16 mL vs. 42 +/- 12 mL; RV end-diastolic volume 190 +/- 33 mL vs. 148 +/- 35 mL, RV end-systolic volume 78 +/- 20 mL vs. 56 +/- 18 mL (p | .05 for all). Normalization of values to body surface area removed the statistical differences for LV volumes, but not for LV mass or RV volumes. With increased age, males showed a significant decrease in volume and

Markov random field (MRF) has been widely used in SAR image segmentation because of the advantage of directly modeling the posterior distribution and suppresses the speckle on the influence of the segmentation result. However, when the real SAR images are nonstationary images, the unsupervised segmentation results by MRF can be poor. The recent proposed triplet Markov field (TMF) model is well appropriate for nonstationary SAR image processing due to the introduction of an auxiliary field which reflects the nonstationarity. In addition, on account of the texture features of SAR image, a fusion image segmentation method is proposed by fusing the gray level image and texture feature image. The effectiveness of the proposed method in this paper is demonstrated by a synthesis SAR image and the real SAR images segmentation experiments, and it is better than the state-of-art methods ...
TY - JOUR. T1 - A unified framework for cross-modality multi-atlas segmentation of brain MRI. AU - Eugenio Iglesias, Juan. AU - Rory Sabuncu, Mert. AU - Van Leemput, Koen. PY - 2013. Y1 - 2013. N2 - Multi-atlas label fusion is a powerful image segmentation strategy that is becoming increasingly popular in medical imaging. A standard label fusion algorithm relies on independently computed pairwise registrations between individual atlases and the (target) image to be segmented. These registrations are then used to propagate the atlas labels to the target space and fuse them into a single final segmentation. Such label fusion schemes commonly rely on the similarity between intensity values of the atlases and target scan, which is often problematic in medical imaging - in particular, when the atlases and target images are obtained via different sensor types or imaging protocols.In this paper, we present a generative probabilistic model that yields an algorithm for solving the atlas-to-target ...

Steady-state free precession (SSFP) is a highly-efficient MRI pulse sequence that has been a fairly recent arrival in the functional MRI realm. Several methods for using balanced SSFP to detect the BOLD signal have been proposed to date and will be discussed in this review. After a brief introduction to the general properties of SSFP, this review describes the quite different approaches of transition-band and pass-band SSFP in terms of functional contrast mechanism. It then discusses the potential advantages of these techniques, followed by their challenges and shortcomings. Finally, it gives an overview of some applications considered to date and the authors perspective on where these techniques are headed. In the spirit of this special issue, the author also includes some of the personal history underlying her own explorations in this area. © 2011 Elsevier Inc.
Aorta dissection is a serious vascular disease produced by a rupture of the tunica intima of the vessel wall that can be lethal to the patient. The related diagnosis is strongly based on images, where the multi-detector CT is the most generally used modality. We aim at developing a semi-automatic segmentation tool for aorta dissections, which will isolate the dissection (or flap) from the rest of the vascular structure. The proposed method is based on different stages, the first one being the semi-automatic extraction of the aorta centerline and its main branches, allowing an subsequent automatic segmentation of the outer wall of the aorta, based on a geodesic level set framework. This segmentation is then followed by an extraction the center of the dissected wall as a 3D mesh using an original algorithm based on the zero crossing of two vector fields. Our method has been applied to five datasets from three patients with chronic aortic dissection. The comparison with manually segmented ...

A 53 year old man was referred for a contrast enhanced cardiovascular magnetic resonance (CMR) scan for assessment of anterior myocardial wall viability. An earlier coronary angiogram had shown a mid left anterior descending artery (LAD) occlusion, and echocardiography had shown mildly reduced global left ventricular function without any other abnormalities. Cine CMR images (steady state free precession sequence) showed a dilated left ventricle (LV) with reduced global systolic function [End-diastolic volume 224 mls (NR 77-195 mls); end-systolic volume 124 mis (NR 19-72 mls); ejection fraction 45%]. There was wall thinning and akinesis of the anteroapical wall and severe hypokinesis of the mid anteroseptal wall. Postgadolinium images (segmented inversion recovery turboFLASH sequence) revealed a prominent LV apical thrombus which measured 1.4 cm at greatest diameter (Figure 1).

Publication date: Feb 07, 2020. Smaller manually-segmented amygdala volumes have been associated with poorer motor and cognitive function in Huntingtons disease (HD). Manual segmentation is the gold standard in terms of accuracy; however, automated methods may be necessary in large samples. Automated segmentation accuracy has not been determined for the amygdala in HD. We aimed to determine which of three automated approaches would most accurately segment amygdalae in HD: FreeSurfer, FIRST, and ANTS nonlinear registration followed by FIRST segmentation. T1-weighted images for the IMAGE-HD cohort including 35 presymptomatic HD (pre-HD), 36 symptomatic HD (symp-HD), and 34 healthy controls were segmented using FreeSurfer and FIRST. For the third approach, images were nonlinearly registered to an MNI template using ANTS, then segmented using FIRST. All automated methods overestimated amygdala volumes compared with manual segmentation. Dice overlap scores, indicating segmentation accuracy, were not ...

This paper presents a semi-automated segmentation method for short-axis cardiac CT and MR images. The main contributions of this work are: 1) using two different energy functionals for endocardium and epicardium segmentation to account for their distinctive characteristics; 2) proposing a dual-background model that is suitable for representing intensity distributions of the background in epicardium segmentation; 3) designing a novel shape prior term that is robust and controllable; and 4) an improved estimation of myocardium thickness by using edge information. Experimental results on cardiac CT, perfusion and cine MR images show that our method is robust and effective for both CT and MR images. © 2009 IEEE ...

Staining methods routinely used in pathology lead to similar color distributions in the biologically different regions of histopathological images. This causes problems in image segmentation for the quantitative analysis and detection of cancer. To overcome this problem, unlike previous methods that use pixel distributions, we propose a new homogeneity measure based on the distribution of the objects that we define to represent tissue components. Using this measure, we demonstrate a new object-oriented segmentation algorithm. Working with colon biopsy images, we show that this algorithm segments the cancerous and normal regions with 94.89 percent accuracy on the average and significantly improves the segmentation accuracy compared to its pixel-based counterpart. © 2008 Elsevier Ltd.

Quantifying flow from phase-contrast MRI (PC-MRI) data requires the vessels of interest be segmented. the effect of segmentation accuracy and provide some criteria that if met would keep errors in circulation quantification below 10% or 5%. Four different segmentation methods were used on simulated and phantom MRA data to verify the theoretical results. Numerical simulations showed that including partial volumed edge pixels in vessel segmentation provides less error than Rabbit polyclonal to AHRR. missing them. This was verified with MRA simulations as the best performing segmentation method generally included such pixels. Further it was found that to obtain a circulation error of less than 10% (5%) the vessel should be at least 4 (5) pixels in diameter have an SNR of at least 10:1 and a maximum velocity to saturation cut-off velocity ratio of at least 5:3. Intro Quantifying blood flow is becoming an increasingly important means by which to study vascular disease with applications not only in ...
Automatic segmentation of anatomical structures is often performed using model-based non-rigid registration methods. These algorithms work well when the images do not contain any large deviations from the normal anatomy. We have previously used such a method to generate patient specific models of hip bones for surgery simulation. The method that was used, the morphon method, registers two- or three-dimensional images using a multi-resolution deformation scheme. A prototype image is iteratively registered to a target image using quadrature filter phase difference to estimate the local displacement. The morphon method has in this work been extended to deal with automatic segmentation of fractured bones. Two features have been added. First, the method is modified such that multiple prototypes (in this case two) can be used. Second, normalised convolution is utilised for the displacement estimation, to guide the registration of the second prototype, based on the result of the registration of the ...

In this paper, two proposed alterations to the dynamic programming parametric active contour model (or snake) are introduced. The first alteration allows the snake to converge to the one-response result of a modified Canny edge detector. The second provides a function that allows a user to preset a-priori knowledge about a given object being detected, by means of curve fitting and energy modification. The results yield accurate segmentations of cross-sectional transverse carotid artery ultrasound images that are validated by an independent clinical radiologist. Utilizing the proposed alterations leads to a reduction of clinician interaction time while maintaining an acceptable level of accuracy for varying measures such as percent stenosis. ...
Medical imaging, such as CT, MRI, shows the information inside the patients body using the non-invasive method so that it is overall better for the doctor´s diagnoses and less painful for patients. However the raw data can only give the material to the doctor, the doctor has to decide for himself what is important and what is not. The computer-aided diagnoses use digital means to process the medical and extract the useful information so that the doctor can make a diagnosis decision easier and quicker. With TelePax-3D option we want to do medical image segmentation three-dimensionally and visualize the segmented object, thereby giving doctors the means of measurement and analysis of the object of interest.. ...
A method to generate an output image that improves observation of a target image viewed on a medium by an optical system is disclosed. The method includes receiving at least one target image by a processing system, receiving at least one parameter by the processing system, defining an error signal associated with the difference between calculated optical system observation of intermediate images and the at least one target image, minimizing the error signal, and generating an output image associated with the intermediate image having the minimized error.

Volume is computed by integrating the flow rate. Any time that data are integrated, decisions must be made about when to re-set the integral. That is, at some point it should be declared that the volume is zero. Typically the flow signal itself is used to re-set the integral. When the flow drops below a certain value, the volume calculation channel is re-set to zero, and subsequent flow is integrated until the flow becomes less than the re-set threshold again, at which point the volume is declared to be zero again. When no subject is breathing through the flow transducer, the signal will, ideally, be very close to zero. In this case, integrating the flow is of no consequence, especially if the signal frequently crosses zero (so that sometimes volume is added and sometimes subtracted) or the re-set threshold (so that the volume keeps getting set back to zero). However, if there is a slight offset in the transducer - if a non-zero signal is consistently indicated when there is no flow, the ...

The embedded image field edit type displays an application-level image definition on the detail screen that can be interactive. Definable behaviors include whether or not to resize the image to fit in the space allocated for the field, the cropping behavior of the image displayed, and the ability to divide the image into cells to elicit different behaviors when different portions of the image are selected.. Each cell in an embedded image field is represented by a child definition to the field in the Editor. This definition type is called an image cell. There will be as many of these image cells as there are cells in the image, which is a multiple of the rows and columns defined for the field. Note that the embedded image field edit type was named the image field edit type in versions of the Agentry Mobile Platform. Starting with version 5.1 and going forward, this field edit type has been named embedded image. This is to distinguish this field edit type from the image capture field, which ...

Die häufigsten Todesfälle in den Industrienationen basieren auf Erkrankungen des Herz-Kreislauf-Systems. Davon entfallen in etwa die Hälfte auf ischämische Herzerkrankungen. Die hohe Sterblichkeitsrate bei Herzkranzgefäßerkrankungen macht eine effiziente Früherkennung solcher Krankheiten nötig. Hierfür hat sich die Perfusionsdiagnostik mittels Magnet-Resonanz-Tomographie (MRT) als sehr vielversprechend herausgestellt. Um die Durchblutung der Herzkranzgefäße sichtbar zu machen, wird ein Kontrastmittel intravenös appliziert. Da die manuelle Analyse solch großer Datenmengen sehr zeitaufwändig ist, wird eine Automatisierung angestrebt. Derzeit existieren allerdings nur Teillösungen einer automatischen Analyse. In dieser Diplomarbeit wurden vier Schritte für die Implementierung einer solchen Anwendung identifiziert: Lokalisierung des Herzens in den Daten, Unterdrückung bzw. Kompensation von Bewegungsartefakten, Segmentierung des Herzmuskels sowie die Analyse der Perfusion des ...

An image processing device includes an image estimation unit that estimates an image prior to the jaggedness occurrence from a jaggedness-occurring image and generates an estimated image prior to the jaggedness occurrence, and a weighting/adding unit that selects a jaggedness-occurring area as a processing target area in the estimated image prior to the jaggedness occurrence, detects a similar area that is a pixel area and similar to the processing target area, and then computes a weight according to the degree of similarity of each detected similar area to the processing target area, and detects a corresponding area in the jaggedness-occurring image to the processing target area and the similar area, and then computes a corrected pixel value of the processing target area of the jaggedness-occurring image through a weighting/adding process to which the weight of a pixel value of the detected corresponding area is applied.
Hi guys,. I want a help in this issue, please look into . In my recent theme design, I put a fixed ( no scroll ) image to the theme background . So every page of the site has this background image, and on top of that image everything loads ( ex. main container , etc ) . But as different different visitors use different screen resolutions and browsers, i used a really big image ( 1460px by 1000px ) as above mentioned background . Because I want to avoid visitors see the background ( i want them to see the image as the background ) . But the problem now is, even after reducing the quality, still the background image ( jpeg file ) is about 500KB which is a big size . And takes a long time to load . I want to solve this problem . Is there any proper way to solve this ? I think splitting the image into few parts would make the site load faster . But I dnt know how to make the allignment for splitted parts ( i want to finally show the complete image without any mis alignment ) correctly .. Thanks ...

  • Therefore this paper deals with the LDCT technique, reading methods and interpretation in lung cancer screening, particularly for those radiologists who have little experience of the technique. (
  • The enormity of the acquired image volume has resulted in substantial workflow challenges to radiologists accustomed to diagnosing from axial slices, and it comes at a time when radiology departments are increasingly resource-constrained. (
  • One measure of effective computer-assisted detection in radiological exams is its ability to focus valuable radiologists' time on interpretation of images. (
  • With the increasing volumes of single- and multimodality data, radiologists will have little time to spend on each examination and will have to focus their attention on interpretation. (
  • Computer-aided detection (CAD) is applied during screening mammography for millions of US women annually, although it is uncertain whether CAD improves breast cancer detection when used by community radiologists. (

  • Although magnetic resonance imaging (MRI) has been used to visualize coronary arteries and to measure flow reserve noninvasively, the utility of MRI for detecting significant LAD stenoses is unknown. (
  • All patients underwent pre-treatment magnetic resonance imaging (MRI) studies including rFOV-DWI and fFOV-DWI. (
  • The software marks even the smallest breast abnormalities on the mammogram image, so the radiologist can take another look and determine if further tests are required. (
  • Biomedical imaging, perhaps, represents the most recognized interface between engineering and medicine, improving clinicians' abilities to screen for and diagnose disease, and monitor the result of treatments. (
  • The book provides a convenient reference for results and current trends in the field of Biomedical Imaging. (
  • The other topics are treated in dedicated chapters, written by leading European researchers in Biomedical Imaging, and provides the reader with up-to-date, state-of-the-art knowledge on emerging areas. (
  • This book is intended to provide a convenient reference for the results and current trends in the field of Biomedical Imaging. (
  • The other topics are addressed in dedicated chapters written by leading European researchers in Biomedical Imaging. (
  • Although availability of automated platforms has proliferated, there is no standard practice for computer-assisted generation of scores for mRNA in situ hybridization (ISH) visualized by brightfield microscopic imaging on tissue sections. (
  • uses multiple images to pinpoint and sample abnormal breast tissue. (
  • A number of tissue section slides are prepared representing all or a relatively large percentage of the tissue sample, and high-resolution digital microscopic images are formed of the sections. (
  • A clustering algorithm forms an image showing the healthy tissue margins, such representation being stored in a file of significantly smaller size than the original photograph. (
  • This study was carried out to investigate whether the electronic portal imaging (EPI) acquisition process could be optimized, and as a result tolerance and action levels be set for the PIPSPro QC-3V phantom image quality assessment. (
  • Images were acquired using a 6 MV beam operating at 100 MU min(-1) and the low-dose acquisition mode. (
  • The optimal settings for the low-dose acquisition mode with respect to image quality and dose were found to be one reset frame and three frame averages. (
  • A DICOM file contains a patient's x-ray image or series of images and other patient-related information (eg, patient name, identification number, acquisition modality) as selected from a library of standardized terms. (
  • In DICOM terminology, the device used to take an image is called an acquisition modality. (
  • In 2003, she was promoted to Head of the Biomedical Image Informatics Group at VRVis. (
