A diagnostic imaging system includes a tomographic scanner 10 which generates sets of anatomical and functional image data. An adaption unit 50 adapts a motion model to a geometry of an object of interest based on a motion averaged volume image representation acquired over a plurality of motion phases. Virtual image data is simulated from the anatomical projection image data with the motion model at the plurality of motion phases. A comparison unit 54 determines a difference between the actual and virtual anatomical image data. If the difference meets a stopping criterion, the motion model is used to correct acquired functional image data, and a corrected functional image is reconstructed therefrom. If not, the motion model is iteratively updated based until the difference meets the stopping criterion.
