Common carotid artery intima-media thickness (IMT), which is usually measured upon ultrasound images, is an important indicator to cardiovascular diseases. This paper proposes a snake model based segmentation method to automatically detect the boundary of intima-media for IMT measurement. In the proposed method, two contours are initialized from line(More)
Segmentation of carotid artery intima-media in longitudinal ultrasound images for measuring its thickness to predict cardiovascular diseases can be simplified as detecting two nearly parallel boundaries within a certain distance range, when plaque with irregular shapes is not considered. In this paper, we improve the implementation of two dynamic(More)
BACKGROUND To propose and test in a preliminary clinical study a novel method for calculating intima-medial thickness (IMT) homogeneity (IMTH). METHODS IMT was measured off-line on every horizontal pixel line along the far wall of the common carotid artery, with previously validated software. IMTH was assessed by the SD, coefficient of variation, and(More)
