Abstract:
1. A method for tracking at least one of an ablation catheter and a circumferential mapping catheter in a fluoroscopic image sequence, comprising: initializing a catheter electrode model of one of an ablation catheter and a circumferential mapping catheter in a first frame of a fluoroscopic image sequence based on input locations of a plurality of electrodes of the one of the ablation catheter and the circumferential mapping catheter in the first frame, wherein the catheter electrode model in the first frame comprises a plurality of template points corresponding to locations of the electrodes of the one of the ablation catheter and the circumferential mapping catheter in the first frame; and tracking the catheter electrode model of the one of the ablation catheter and the circumferential mapping catheter in a second frame of the fluoroscopic image sequence by:
