ABSTRACT:
A method for assisting the planning of an interventional biventricular pacing procedure includes segmenting an image dataset of a heart of a patient to extract a surface of a left ventricle (LV) and a LV myocardium of the patient's heart, utilizing the segmented image dataset to divide the LV into myocardial segments or into a plurality of short axis slices, and detecting wall motion of each short axis slice of phases of a cardiac cycle of the patient's heart with respect to a reference phase. The method also includes localizing a region most recently attaining maximum displacement and a region most recently attaining maximum velocity, and generating 2D or 3D renderings including renderings indicating at least one of time delays of contraction, a maximum displacement, or a maximum velocity.
