Abstract :
Multiple detector row computed tomography (MDCT) cardiac angiography provides a large amount of data concerning multiple cardiac phases which are not often considered. Segmentation is a first step towards exploring how this additional data can be used to perform left ventricle functional analysis or myocardial perfusion assessment. We present preliminary results regarding the assessment of inter-observer variability for a semi-automatic (multi-phase) segmentation tool for the left-ventricle.
