<p>In order to accurately display the head-feet direction on a display unit regardless of the x-ray plane detector insertion direction, an x-ray image diagnostic device is provided with: an x-ray tube (1) for irradiating a test subject with x-rays; a grid (2) for removing a scattered ray component caused by the test subject (20); an x-ray plane detector (3) that detects transmitted x-rays of the test subject (20) and outputs image data, and is positioned so as to face the x-ray tube (1); an image display unit (6) for displaying an image based on image data; a grid stripe direction determination unit (5b) for determining whether the stripe direction originating from the grid included in the image data is vertical or horizontal; and an image rotation unit (5d) for rotating the image on the basis of the determination result from the grid stripe direction determination unit, in a manner such that the head direction in the region of the test subject (20) captured in the image aligns with the top direction on the display screen in the image display unit (6). Therein, the image display unit (6) displays the rotated image.</p> |
