Abstract :
This work presents a fully automatic method for regional myocardial contraction and motion assessment in cardiac cine MRI studies. The prerequisite of segmenting the left ventricle at all temporal phases of the study, is accomplished using a statistical model-based algorithm (3D-ASM). Subsequent functional analysis includes the assessment of LV global functional indexes like e.g. time-volume curves, ejection fraction, stroke volume and cardiac output, as well as regional function parameters, like segmental wall motion, thickening and dyssynchrony delays
