Article
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 ...

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 ...

Quantitative analysis of brain white matter lesions in multiple sclerosis subjects: Preliminary findings
(2008)In this study the value of magnetic resonance image (MRI) shape and texture analysis was assessed in multiple sclerosis (MS) subjects, both in differentiating between normal and abnormal tissue and in assessing disease ...

Quantitative analysis of brain white matter lesions in multiple sclerosis subjects
(2009)In this study the value of magnetic resonance image (MRI) shape and texture analysis was assessed in multiple sclerosis (MS) subjects, both in differentiating between normal or normal appearing and abnormal tissue and in ...

Article
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 ...

A comparison of ultrasound intima media thickness measurements of the left and right common carotid artery
(2013)The intima-media thickness (IMT) of the common carotid artery (CCA) is an established indicator of cardiovascular disease (CVD). There have been reports about the difference between the left and the right sides of the CCA ...

Manual and automated media and intima thickness measurements of the common carotid artery
(2009)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 ...

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 ...

Atherosclerotic carotid plaque segmentation
(2004)Atherosclerosis is the major cause of heart attack and stroke in the western world. In this paper we present a computerized method for segmenting the athrerosclerotic carotid plaque from ultrasound images. The method uses ...

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 ...

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 ...

Brain MR image normalization in texture analysis of multiple sclerosis
(2009)A problem that occurs in texture analysis and quantitative analysis of magnetic resonance imaging (MRI), is that the extracted results are not comparable between consecutive or repeated scans or, within the same scan, ...

Article
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 ...

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 ...

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 ...
