Principle of CBCT and MDCT. a In CBCT, cone-shaped X-ray beam reaches a flat detector after a single rotation of the gantry around the patient. b In MDCT, narrowly collimated, fan-shaped beam and multiple linear detectors rotate around the patient to acquire multiple image sections per rotation. In both techniques volumetric images are reconstructed into a 3-D volume dataset of images
