Dynamical Segmentation of the Left Ventricle in Echocardiographic Image Sequences
Abstract
This paper presents a new methodology for the analysis of echocardiographic image sequences. The echocardiographic medical exam is a frequent practice in the cardiology clinic, and generally there is bi-dimensional echocardiographic equipment We have developed a new processing chain that will allow a medical diagnosis issued from a 3D reconstruction of the ultrasonic images. The project is divided into several 3D modules: Acquisition, Filtering, Segmentation, Reconstruction, and visualization. Inside of the processing chain, the segmentation module of ultrasonic images has always been a problem. In this paper, we propose two different methods for the 3D segmentation. A model of 3D Snakes and a front propagation model that allow an accurate segmentation and reconstruction of the internal wall of the ventricle. From these segmentation methods, some important medical parameters are computed : ejection fraction, cardiac index, ventricle volume, etc.
