A plurality of projection images are acquired over an angular range during the slow rotation of a C-arm gantry having a source and detector. Phase-specific reconstructions are generated from the plurality of projections, wherein each phase-specific reconstruction is generated generally from projections acquired at or near the respective phase. In one embodiment, a plurality of motion estimates are generated based upon the phase-specific reconstructions. One or more motion-corrected reconstructions may be generated using the respective motion estimates and projections. The motion-corrected reconstructions may be associated to form motion-corrected volume renderings.

Method and apparatus for correcting motion in image reconstruction

A CT imaging system includes a rotatable gantry having an opening to receive an object to be scanned. A plurality of x-ray emission sources are attached to the rotatable gantry, each x-ray emission source configured to emit x-rays in a conebeam toward the object. The CT imaging system also includes a plurality of x-ray detector arrays attached to the gantry and positioned to receive x-rays passing through the object. At least one x-ray detector array of the plurality of x-ray detector arrays is configured to receive x-rays from more than one x-ray emission source.
