Patent ID: 8446408

Claim:
A method for generating or reconstructing three-dimensional (3D) images based on image projection data corresponding to a structure of interest, the method comprising: acquiring a plurality of image projections corresponding to a structure of interest in at least first and second motion phases; monitoring the motion phases of the structure of interest as the plurality of image projections are acquired; adapting a 3D shape model to the image projections acquired in the first motion phase of the structure of interest to represent said structure of interest in the first motion phase, thereby yielding an adapted 3D shape model in the first motion phase; adapting the 3D shape model to the image projections acquired in the second motion phase to generate a second adapted 3D model representing the structure of interest in the second motion phase; generating a motion vector field based on said first and second adapted 3D shape models and said motion of said structure of interest; and reconstructing a 3D image of the structure of interest in a selected motion phase using said motion vector field and the first and second motion phase projection images.
