Abstract
According to one embodiment, the X-ray diagnosis apparatus includes an X-ray detector, X-ray diaphragm apparatus, and processing circuitry controlling the X-ray diaphragm apparatus to shield the X-rays from passing through a X-ray filter outside an aperture region or a partial region during a transition from first fluoroscopy employing an X-ray filter to second fluoroscopy employing diaphragm blades, generating a first and second fluoroscopic image during the first and second fluoroscopy respectively, generating a composite image during the second fluoroscopy by combining a non-ROI image of the first fluoroscopic image and a ROI image of the second fluoroscopic image, and displaying the first fluoroscopic image and the composite image on the display during the first and second fluoroscopy respectively.
