The position information acquisition mechanism acquires position information of a treatment device inserted into the patient. The position information corrector corrects the position information of the treatment device based on the position information of the treatment device and treatment device information of the image data for positional deviation correction, collected by X-ray imaging in the second imaging mode. The display displays the reference image data to which the corrected position information is added.
