摘要： A ventricular epicardium registration method (60) involves three phases. The first phase (P62) is an identification of one or more anatomical features invisible within ultrasound images (41) of a ventricular epicardium of a heart (10). The second phase (P61) is a representation of the anatomical feature(s) visible within X-ray images (31) of the ventricular epicardium of the heart. The third phase (P63) is a registration of the ultrasound images (41) and the X-ray images (31) of the ventricular epicardium of the heart based on the representation of the anatomical feature(s) invisible in the ultrasound images (41) and on the identification of the anatomical feature(s) visible within 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).

摘要： A system and method for ablation planning includes defining (502) shapes and sizes for one or more ablation volumes based on probability of treatment, and determining (510) a target volume to be treated. A procedure plan is provided (516) by determining a number and location of planned ablations within the target volume using the one or more ablation volumes. A joint probability distribution (520) is determined for at least two planned ablations in the target volume. A final configuration is visualized (530) to determine if plan objectives are met based on a probability of treatment for the target volume.

摘要： Example embodiments are directed to a video image display system that includes a motion estimation circuit (112), a front-end motion compensation circuit (110), and a video signal conversion circuit (134, 136). The motion estimation circuit generates motion vectors as a function of an incoming video signal, the front-end motion compensation circuit receives and processes the incoming video signal as a function of the motion vectors for general video display, and the video signal conversion circuit receives the processed video signal from the front-end motion compensation circuit and generates a display signal for a specific video display as a function of both the processed video signal and the motion vectors. In one implementation, a scaler (120) is implemented to scale the video signal for a particular display type, with components of the motion compensation being implemented for use with the scaler.
