FUSION OF CARDIAC 3D ULTRASOUND AND X-RAY INFORMATION BY MEANS OF EPICARDIAL SURFACES AND LANDMARKS

摘要

A ventricular epicardium registration method (60) involves three phases. The first phase (P61) is an identification of one or more anatomical features visible within ultrasound images (41) of the ventricular epicardium of the heart (10). The second phase (P62) is an identification of the anatomical feature(s) visible within X-ray images (31) of a ventricular epicardium of a heart (10). The third phase (P63) is a mapping of the ultrasound images (41) and the X-ray images (31) of the ventricular epicardium of the heart (10) based on the identification of the anatomical feature(s) visible within the ultrasound images (41) and the X-ray images (31). Examples of the anatomical feature(s) include, but are not limited to, a portion or an entirety of an epicardial surface (11, 12) and a coronary sinus vein (13).
