Active contours are a popular method for automatic extraction of object boundaries basedon image features in medical images. However, in short axis cardiac MR images, they fail to givecorrect results due to the presence of papillary muscles along the left ventricular endocardiumboundary. We propose a new automatic cardiac contour propagation method based on activecontours. The method can be used to propagate cardiac contours that conform an initial manualsegmentation, by exploiting information in adjacent images. In this paper, we present the results ofthe optimization and extensive validation of our method, which was found to be robust and accuratefor the delineation of the LV endocardium, LV epicardium and RV endocardium contours.Additionally, the processing time is reduced significantly compared with manual contour delineation.
