Patent Number: 6,480,574

Title: X-ray diagnostic apparatus

Abstract: An X-ray tube and an X-ray detector are supported by an arm in such a manner that a distance between the X-ray tube and an image reception plane of the X-ray detector can be changed. A grid is arranged on the image reception plane of the X-ray detector. The arm is supported by an arm support apparatus in such a manner that an angle of the arm can be changed. Moire image data files obtained by the grid are stored in a storage device in association with the distance between the X-ray tube and the image reception plane of the X-ray detector and the angle of the arm. Image data outputted from the X-ray detector is corrected by the moire correction circuit based on the moire image data selectively read from the storage device in accordance with the distance and the angle.
