Abstract

A method for forming an image reconstructs a volume image according to X-ray projection images acquired at acquisition angles. The full volume image is partitioned to form at least a first and a second non-overlapping sub-volume. Within each sub-volume, forward projection images for the sub-volume are calculated, with the corresponding forward projection images computed at the acquisition angles, and with intermediate forward projection images at angles between the acquisition angles. A weight factor relates the contribution of each pixel in the X-ray projection images to each sub-volume at each acquisition angle. Synthesized sub-volume projection images are formed according to the calculated weight factors and acquired projection images in each sub-volume. Synthesized sub-volume projection images form synthesized projection images for the full volume image. A second volume image is reconstructed according to the acquired X-ray projection images and the synthesized projection images. The reconstructed second volume image is displayed, stored, or transmitted.
