Abstract

A new method of segmentation of ultrasound Carotid Artery (CA) has been proposed. Atherosclerosis is the thickening and narrowing of the arteries due to formation of plaque on the walls of the artery. It is one of the major causes of stroke.Intima-media thickness (IMT) is now being considered as an indicator of atherosclerosis. CA segmentation is based on the improvised snake’s initialization method after the speckle reduction and normalization. All the images obtained here are b-mode longitudinal US images. This computerized method shows closer results as that obtained from manual measurements
