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; identifying an observed curve for each of a plurality of different phases of the physiological cycle from the first sequence of CINE acquisition data; generating a fitted curve for each of the observed curves; generating a motion model of the curved medical device as a function of the fitted curves; obtaining a second sequence of frames of fluoroscopy data, the fluoroscopy data of the frames representing the curved medical device over the physiological cycle; predicting the shape of the curved medical device in the frames of the fluoroscopy data as a function of the motion model of the curved medical device; and generating a fluoroscopy image of the curved medical device, the fluoroscopy image indicating the predicted curved medical device.
