Myocardial boundary extraction using coupled active contours

Automatic extraction of object boundaries in medical images using active contours is a popular research item. A problem with active contours is that they may fail to give correct results in cases of low contrast, noise or the neighbourhood of other edges. If there exists a geometrical relation between several boundaries this may be exploited to improve the robustness of active contours. In this way a set of coupled active contours results. This paper describes the simultaneous extraction of epi- and endocardial boundaries using a set of coupled active contours in MR short axis cine recordings.
