3D-2D Adaptive Shape Model Supported Motion Compensated Recnstruction

摘要

A method for generating or reconstruction of three-dimensional (3D) images corresponding to a structure of interest ( 60 ) including: acquiring a plurality of image projections corresponding to a structure of interest ( 60 ); applying a shape model ( 66 ) at a selected 3D seed point ( 64 ); and adapting the shape model ( 66 ) to represent the structure of interest ( 60 ), yielding an adapted shape model. A system for generation and reconstruction of three-dimensional (3D) images. The system ( 10 ) includes: an imaging system ( 12 ) configured to provide projection data corresponding to a structure of interest ( 60 ); and a controller ( 50 ) in operable communication with the imaging system ( 50 ). The controller ( 50 ) is configured to: receive the projection data, ( 64 ); apply a shape model ( 66 ) at a selected 3D seed point ( 64 ); and adapt the shape model ( 66 ) to represent the structure of interest ( 60 ), thereby yielding an adapted shape model.
