Abstract

Fast marching method is an important approach for boundary detection in medical images. However, it is difficult to be applied into echocardiographic images for the inevitable noise and artifacts. This paper presents an improved fast marching approach for boundary detection of echocardiographic images, and validates this approach by detecting and tracking the endocardial boundary in echocardiographic images. Firstly, the traditional fast marching algorithm is applied to the echocardiographic images and the existing problems of the traditional fast marching algorithm are given. Then, the algorithm is improved by introducing the advancing front’s average energy into the speed term, instead of determining the speed term only with the local image features. The experimental results show that the improved algorithm is very effective and robust.
