MOTION CORRECTION WITH LOCALLY LINEAR EMBEDDING FOR ULTRAHIGH RESOLUTION COMPUTED TOMOGRAPHY
A CT apparatus in which the x-ray source is coupled to a source robotic arm and the detector is coupled to a detector robotic arm. A motion correction module utilizes a locally linear embedding motion correction algorithm to estimate the geometry-describing parameters associated with the positions of the source and detector and the angle of the detector. These estimates are used to reconstruct the image data and produce corrected images with fewer errors resulting from patient movement, misalignments, and coordination issues in the system.
