Abstract An apparatus and method for reconstructing image data for a region are described. A radiation source and an array of detectors located on opposed sides of a region are used to generate scan data for the region from a plurality of diverging radiation beams. The cone beam scan data for the region are converted into parallel beam scan data. The reordered parallel beam scan data are used to generate image data for a set of oblique image slices for the region, wherein the oblique image slices form a non-perpendicular angle with the longitudinal axis of the region.
