Abstract

The invention describes a method of extracting mechanical activation of the left ventricle (1_LV) from a sequence (20) of contrasted X-ray fluoroscopy images (2), said method comprising the steps of: processing the image sequence (20) to perform segmentation of the coronary veins (1_CS); annotating branches (10) of the segmented coronary veins; tracking the positions of the annotations (L1, ..., L6) throughout the fluoroscopy image sequence (20); computing the principle components of the motion of the annotations (L1, ..., L6) from the tracked positions; projecting the motion of the annotations (L1, ..., L6) to the axis corresponding to a first principle component; and analyzing the resulting motion curves (C, C) to identify a latest activating region of the left ventricle (1_LV).
