摘要： PROBLEM TO BE SOLVED: To provide a method for detecting and tracking an ablation catheter tip in a fluoroscopic image sequence with a plurality of frames.
SOLUTION: Catheter tip candidates are detected in each frame of the fluoroscopic image sequence using marginal space learning. The detected catheter tip candidates are then tracked over all the frames of the fluoroscopic image sequence in order to determine a place of an ablation catheter tip location in each frame.
