1. A method for modeling in angiography, the method comprising: obtaining a first sequence of frames of CINE acquisition data, the CINE acquisition data of the frames representing a curved medical device over a physiological cycle; modeling the curved medical device as a function of phase of the physiological cycle, the modeling providing a time-varying model of the curved medical device; obtaining a second sequence of frames of fluoroscopy data, the fluoroscopy data of the frames representing the curved medical device over the physiological cycle; tracking the curved medical device in the frames of the fluoroscopy data as a function of the time-varying model of the curved medical device; and generating a fluoroscopy image of the curved medical device, the fluoroscopy image indicating the curved medical device from the tracking.
