Abstract

In this paper an algorithm to detect and elastically match the contours of the epicardial walls of the left ventricle (LV) in cardiac phase-resolved 2-D Magnetic Resonance (MR) images is presented. For both tasks, dynamic programming (DP) is used. A mask conforming to the six segment model of the LV is fitted on a reference image and propagated utilizing the elastic matching information. At its present form the algorithm requires minimal parameter corrections among different sets of cine MRI images. Future extensions include comparisons with contours hand labeled by imaging experts.
