Manual and automated intima-media thickness and diameter measurements of the common carotid artery in patients with renal failure disease
(2014)The objective of this study was to investigate differences in intima-media thickness (IMT) and diameter (D) measurements of the common carotid artery (CCA) in ultrasound imaging in normal subjects and renal failure disease ...

Matrix decomposition RBF algorithm for solving 3D elliptic problems
(2009)In this study, we propose an efficient algorithm for the evaluation of the particular solutions of three-dimensional inhomogeneous elliptic partial differential equations using radial basis functions. The collocation points ...

Media thickness measurement of the common carotid artery
(2007)The intima-media thickness (IMT) of the common carotid artery (CCA) is widely used as an early indicator of the development of cardiovascular disease (CVD). It was proposed but not thoroughly investigated that the media ...

Non-stationary texture segmentation using an AM-FM model
(1997)We present a novel method for segmenting non-stationary textures. Our approach uses a multidimensional AM-FM representation for the texture, and provides the FM features to an SOFM-LVQ neural network system that performs ...

One-to-many neural network mapping techniques for face image synthesis
(2012)This paper investigates the performance of neural network-based techniques applied to the problem of defining the relationship between a particular type of variation in face images and the multivariate data distributions ...

Optimal scanning, display, and segmentation of the International Labor Organization (ILO) x-ray images set for pneumoconiosis
(2001)A method for scanning and displaying chest radiographs (x-rays) is presented. The new method treats scanning independent of display, allowing for maximum information content to be captured during the scanning process, and ...

Optimizing the utility function-based self-adaptive behavior of context-aware systems using user feedback
(2008)The vision of ubiquitous computing is about numerous devices embedded in our every-day environment, designed to serve humans in a non-obtrusive manner while minimizing the required user attention. These devices are expected ...

A review of noninvasive ultrasound image processing methods in the analysis of carotid plaque morphology for the assessment of stroke risk
(2010)Noninvasive ultrasound imaging of carotid plaques allows for the development of plaque-image analysis methods associated with the risk of stroke. This paper presents several plaque-image analysis methods that have been ...

A screening system for the assessment of opacity profusion in chest radiographs of miners with pneumoconiosis
(Institute of Electrical and Electronics Engineers Inc., 2002)The aim of this study was to develop a screening system of chest radiographs of miners with pneumoconiosis. Chest radiographs were of coal mine or silica dust exposed miners participating in a health screening program. A ...

Segmentation of atherosclerotic carotid plaque in ultrasound video
(2012)The degree of stenosis of the common carotid artery (CCA) but also the characteristics of the arterial wall including plaque size, composition and elasticity represent important predictors used in the assessment of the ...

Segmentation of the common carotid intima-media complex in ultrasound images using active contours
(2012)The segmentation of the intima-media complex (IMC) of the common carotid artery (CCA) wall is important for the evaluation of the intima media thickness (IMT) on B-mode ultrasound (US) images. The IMT is considered an ...

Snakes based segmentation of the common carotid artery intima media
(2007)Ultrasound measurements of the human carotid artery walls are conventionally obtained by manually tracing interfaces between tissue layers. In this study we present a snakes segmentation technique for detecting the ...

Video segmentation of the common carotid artery intima media complex
(2012)The correct identification of the intima-media thickness (IMT) of the common carotid artery (CCA) walls has a high clinical relevance as it represents one of the most reliable predictor for future cardiovascular events. ...
