X-ray computed tomography device, e.g. medical X-ray computed tomography device, has X-ray data acquisition system for acquisition of X-ray projection data from X-rays based on types of number of X-ray data acquisition views per rotation
The device has an X-ray data acquisition system (25) for acquisition of X-ray projection data from X-rays, which are let out through an object based on types of number of X-ray data acquisition views per rotation. The X-rays are disposed between an X-ray tube (21) and an X-ray detector (24), which detects the X-rays that are opposite to the tube, when the tube and detector are rotated around an intermediate rotation center. A central processing unit (3) reconstructs the projection data, and a monitor (6) displays a reconstructed tomography image.
