Abstract:
1. A computer-implemented method for producing images of the walls of a human heart comprising: capturing a plurality of 4D surface registration points of the walls of the human heart from (i) a plurality of ultrasound images of the walls of the heart acquired at different points of a cardiac cycle by a catheter comprising a position sensor, wherein the ultrasound images are acquired from within the heart without having the catheter touch the walls of the heart, (ii) data regarding the position of the catheter when the ultrasound images were acquired by the catheter based on the position sensor, and (iii) data regarding the time that the ultrasound images were acquired; and registering, in space and time, a high-resolution 4D model of the heart with the plurality of 4D surface registration points.
