<p>PROBLEM TO BE SOLVED: To improve a moire correction precision in an X-ray diagnostic apparatus. SOLUTION: This X-ray diagnostic apparatus is provided with an X-ray bulb 12, an X-ray detector 13, a grid 14 disposed on a image receiving surface of the X-ray detector, an arm 18 supporting the X-ray bulb and the image receiving surface of the X-ray detector so as to change the distance between the X-ray bulb and the image receiving surface of the X-ray detector, an arm supporting device 19 supporting the arm in such a state as being changeable the angle of the arm, a storage device 29 storing multiple files of moire image data by the grid by relating, at least, one of the distance and the angle, and a moire correction circuit 27 correcting the image data outputted from the X-ray detector based on the moire image data selectively read out from the storage device according to, at least, one of the distance and the angle.</p> |
