Abstract

A method and system for real time stent enhancement on a live 2D fluoroscopic scene is disclosed. A motion compensated stent enhancement image is generated from a first set of frames in a fluoroscopic image sequence. A weighting field is generated based on the motion compensated stent enhancement image. For each new frame in the fluoroscopic image sequence that is received, the stent is enhanced in the new frame by compounding the new frame with the motion compensated stent enhancement image using the weighting field.
