<p>PROBLEM TO BE SOLVED: To provide an X-ray image diagnostic apparatus that facilitates phantom position confirmation and reduces a burden on an operator in performing photographic system accuracy evaluation.SOLUTION: A calculation part 57 of an X-ray image diagnostic apparatus 1 calculates a shape feature amount of a phantom 6 from an X-ray image, and determines whether or not it coincides with the feature amount information stored in a storage part 53 beforehand so as to determine whether or not the arrangement of the phantom 6 is appropriate. When the arrangement of the phantom 6 is determined as being appropriate, a control part 55 performs photographic system accuracy evaluation processing using the X-ray image. When the arrangement of the phantom 6 is not appropriate, error notification is made. Or, the relative position of a top plate 4 and the photographic system 2 is moved and adjustment is made so that the phantom 6 is arranged in an appropriate position.</p> |
