Abstract:
A method of reconstructing image data for a region having a longitudinal axis, comprising:providing a radiation source and an array of detectors on opposed sides of the region, the radiation source emitting radiation toward the array of detectors to generate a plurality of diverging radiation beams received by the array of detectors, at least one of the radiation source and the array of detectors being rotatable about the longitudinal axis through a plurality of projection angles to scan the region to generate diverging beam scan data for the region;converting the diverging beam scan data for the region into parallel beam scan data for the region;defining at least one oblique image slice for the region, said oblique image slice being oblique with respect to the longitudinal axis; andusing at least a portion of the parallel beam scan data for the region, generating image data for the at least one oblique image slice.
