Abstract
According to one embodiment, the X-ray image diagnosis apparatus comprises an X-ray generator, an X-ray restriction unit, a first X-ray detector, a second X-ray detector, and a drive. The X-ray generator generates X-rays to be applied to a subject. The X-ray restriction unit is disposed between the subject and the X-ray generator to restrict X-rays outside an opening region which is formed using a metal plate. The first X-ray detector has a first detection region in which X-rays that pass through the subject are detected. The second X-ray detector has a second detection region which is smaller than the first detection region and which has a high spatial resolution. The drive moves the first and second X-ray detectors so that the second detection region includes an irradiation region of the subject formed by the opening region.
