摘要： X-ray imaging apparatus is provided which includes a moveable C-shaped arm (16) with an X-ray source (12) mounted at one end and a linear camera array (14) at the other end. The arm is driven relative to a patient and scans the patient's body with a narrow, fanned beam. A position encoder (150) generates timing signals which are used to synchronise the motion of the arm with imaging circuits, to generate image signals of a relatively large object.
