Abstract: In this paper a method for segmentation of the endocardium in Late Gadolinium Enhanced Cardiac Magnetic Resonance (LGE-CMR) images is presented and combined with a previously proposed method for segmentation of the epicardium. The method is fully automatic and based on utilizing a priori knowledge about the type of images. No other image modalities, like CINE images, are used. Using a combination of a rough a priori model and preprocessed images, an a posteriori model is built. The final segmentation step is performed in the polar domain. We compare our results on a set of 395 images from 54 patients with segmentation using marker controlled watershed with different gradient images and different markers. The proposed method gives a mean Dice and Jaccard indices over all images as 0.85 and 0.74 respectively.
