Active Model Based Carotid Ultrasonic Data Segmentation

Abstract

Abstract.To diagnose cardiovascular diseases, the most significant mortality causes in industrialized countries, the study of the carotid artery wall plays a preferential part. This paper presents a three dimensional active model based carotid ultrasonic data segmentation. A C1 continuous surface, defined by a deformable skeleton and envelope, includes the Y-shape topology and gray level as a priori knowledge. It is automatically fitted to a sequence of 2.5D ultrasonic branching data by an iterative quadratic method. The quality of the fit is illustrated by figures. Result of this 3D fitting can be used as initial position for quantification of the intima-media thickness.
