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.
