AM-FM representations for the characterization of carotid plaque ultrasound Images
(2008)Stroke is the third leading cause of death in the western world and a major cause of disability in adults. The objective of this work was to investigate the use of AM-FM representations for the characterization of carotid ...

Comparative evaluation of despeckle filtering in ultrasound imaging of the carotid artery
(2005)It is well-known that speckle is a multiplicative noise that degrades the visual evaluation in ultrasound imaging. The recent advancements in ultrasound instrumentation and portable ultrasound devices necessitate the need ...

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 ...

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 ...

An integrated teleconsultation system for the evaluation of the risk of stroke
(Plymouth University, 2005)This paper describes the design and development of an integrated teleconsultation system for the estimation of the annual incidence of stroke related to carotid atherosclerotic plaque and the detection of high risk and low ...

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 ...

Polymeric theranostics: Using polymer-based systems for simultaneous imaging and therapy
(2013)Polymer-based nanomedicine is a large and fast growing field. Polymer-based systems have been extensively used as therapeutic carriers as well as bioimaging agents for example in tumour diagnosis. However, fewer polymeric ...

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 ...

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 ...

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 ...

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 ...

Article
Texture-based classification of atherosclerotic carotid plaques
(2003)There are indications that the morphology of atherosclerotic carotid plaques, obtained by high-resolution ultrasound imaging, has prognostic implications. The objective of this study was to develop a computer-aided system ...

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 ...
