An X-ray radiography unit ( 103 ) irradiates a patient with X-rays from a first X-ray tube ( 127 ) to obtain an X-ray two-dimensional radiographic image (PI). An X-ray CT unit ( 101 ) irradiates the patient with X-rays from a second X-ray tube ( 125 ) and acquires projection data, to reconstruct an image using the acquired projection data, thereby obtaining a tomography image (TI). A control unit ( 50 ) defines correspondences between position information of the patient located in the X-ray radiography unit and position information of the patient located in the X-ray CT unit. The clearly demonstrated positional correspondence in the X-ray hybrid diagnosis system can facilitate a diagnosis and obviates the need for extra X-raying operations, to thereby ease the strain placed on patients.
