Basic principle of digital tomosynthesis (DT). DT acquires image data by a single sweep of an X-ray tube, with a range of 8 to 40°, whereas that of cone beam computed tomography is 360°. The X-ray is detected by digital flat panel detectors (FPD), which are either in the same position or may move in the opposite direction to the X-ray tube depending on the tables.
