Use of local or global quality of match to estimate cone beam CT reconstruction artifact correction weight in image registration

摘要

Disclosed are systems for and methods of registering a deformable image with a reference image subject to a local or global quality of match. These systems and methods may use the quality of match to reduce effects of artifacts within the deformable image or the reference image on a deformation algorithm. The registration includes modifying the deformable image to match similar features in the reference image. The systems include a deformation engine configured for performing the deformation algorithm subject to the local or global quality of match. The systems and methods allow for correcting for cone beam computed tomography artifacts in one or more of the images.
