AM-FM texture image analysis of the intima and media layers of the carotid artery
(2009)The purpose of this paper is to propose the use of amplitude modulation-frequency modulation (AM-FM) features for describing atherosclerotic plaque features that are associated with clinical factors such as intima media ...

Atherosclerotic carotid plaque texture variability in ultrasound video
(Springer Verlag, 2015)Ultrasound video of the common carotid artery (CCA) combined with texture feature analysis has the potential in differentiating between asymptomatic and symptomatic atherosclerotic carotid plaque and is used widely for the ...

Completely automated multiresolution edge snapper (CAMES): A new technique for an accurate carotid ultrasound IMT measurement and its validation on a multi-institutional database
(2011)Since 2005, our research team has been developing automated techniques for carotid artery (CA) wall segmentation and intima-media thickness (IMT) measurement. We developed a snake-based technique (which we named CULEX 1,2), ...

Completely automated multiresolution edge snapper-A new technique for an accurate carotid ultrasound IMT measurement: Clinical validation and benchmarking on a multi-institutional database
(2012)The aim of this paper is to describe a novel and completely automated technique for carotid artery (CA) recognition, far (distal) wall segmentation, and intima-media thickness (IMT) measurement, which is a strong clinical ...

De-speckle filtering in ultrasound imaging of the carotid artery
(2002)The main objective of this paper is to evaluate the classification performance of de-speckle filtering on ultrasound imaging of the carotid atherosclerotic plaque. The following procedure was investigated on 230 images ...

Despeckle filtering of ultrasound images
(Springer New York, 2011)It is well known that speckle is a multiplicative noise that degrades the visual evaluation in ultrasound imaging. This necessitates the need for robust despeckling techniques for both routine clinical practice and ...

Article
Effect of posture change on the geometric features of the healthy carotid bifurcation
(2011)Segmented cross-sectional MRI images were used to construct 3-D virtual models of the carotid bifurcation in ten healthy volunteers. Geometric features, such as bifurcation angle, internal carotid artery (ICA) angle, ...

Global optimization for motion estimation with applications to ultrasound videos of carotid artery plaques
(2010)Motion estimation from digital video is an ill-posed problem that requires a regularization approach. Regularization introduces a smoothness constraint that can reduce the resolution of the velocity estimates. The problem ...

Article
An integrated system for the segmentation of atherosclerotic carotid plaque
(2007)In this paper, we propose and evaluate an integrated system for the segmentation of atherosclerotic plaque in ultrasound imaging of the carotid artery based on normalization, speckle reduction filtering, and four different ...

M-mode state based identification in ultrasound videos of the atherosclerotic carotid plaque
(2010)Monitoring the wall and plaque changes in the carotid artery (CA) can provide useful information for the assessment of the atherosclerotic disease. Using a motion mode (M-mode) image, detailed information may be obtained ...

Multi-scale AM-FM motion analysis of ultrasound videos of carotid artery plaques
(2012)An estimated 82 million American adults have one or more type of cardiovascular diseases (CVD). CVD is the leading cause of death (1 of every 3 deaths) in the United States. When considered separately from other CVDs, ...

Article
Multiscale amplitude-modulation frequency-modulation (AM-FM) texture analysis of ultrasound images of the intima and media layers of the carotid artery
(2011)The intima-media thickness (IMT) of the common carotid artery (CCA) is widely used as an early indicator of cardiovascular disease (CVD). Clinically, there is strong interest in identifying how the composition and texture ...

Article
Plaque imaging using ultrasound, magnetic resonance and computer tomography: A review
(2005)Different classifications have been proposed in the literature for the characterization of atherosclerotic plaque morphology, resulting in considerable confusion. For example plaques containing medium of high level uniform ...

Quality evaluation of ultrasound imaging in the carotid artery
(2004)Image quality assessment plays an important role in various image-processing applications. In this work we evaluate image quality criteria based on mean square error, signal to noise error, and quality and structural ...

Article
Quality evaluation of ultrasound imaging in the carotid artery based on normalization and speckle reduction filtering
(2006)Image quality is important when evaluating ultrasound images of the carotid for the assessment of the degree of atherosclerotic disease, or when transferring images through a telemedicine channel, and/or in other image ...

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 ...

Ultrasound image quality evaluation
(Institute of Electrical and Electronics Engineers Inc., 2003)The objective of this work was to evaluate the image quality of two different ultrasound image scanners before and after de-speckle filtering. The evaluation was made by statistical and texture analysis, as well as by ...

Ultrasound image texture analysis of the intima and media layers of the common carotid artery and its correlation with age and gender
(2009)The intima-media thickness (IMT) of the common carotid artery (CCA) is widely used as an early indicator of cardiovascular disease (CVD). It was proposed but not thoroughly investigated that the composition and texture of ...

Ultrasound imaging media layer texture analysis of the carotid artery
(2008)The intima-media thickness (IMT) of the common carotid artery (CCA) is widely used as an early indicator of cardiovascular disease (CVD). It was proposed but not thoroughly investigated that the media layer (ML), its ...

Ultrasound intima-media thickness and diameter measurements of the common carotid artery in patients with renal failure disease
(2013)Although the intima-media thickness (IMT) of the common carotid artery (CCA) is an established indicator of cardiovascular disease (CVD), its relationship with renal failure disease (RFD) is not yet established. In this ...
