<p>Provided are an X-ray image diagnostic device, an X-ray exposure control method, and a program, wherein an appropriate radioscopic X-ray output condition is obtained even when a subject moves during radioscopy. The X-ray image diagnostic device is provided with an X-ray generation means (1) for generating X-rays, an X-ray detection means (2) for detecting transmitted X-rays transmitted through the subject and outputting image data indicating the X-ray intensity of the transmitted X-rays, a region-of-interest setting means (7) for setting a plurality of regions of interest on an X-ray intensity distribution image based on the image data, an X-ray intensity calculation means (8) for calculating the representative values of indexes indicating the X-ray intensities of the respective regions of interest, an X-ray intensity selection means (9) for selecting one representative value from among the representative values of the X-ray intensities of the plurality of regions of interest, and an X-ray exposure control means (5) for performing exposure control of the X-ray generation means (1) on the basis of the selected representative value of the X-ray intensity.</p> |
