PROBLEM TO BE SOLVED: To raise efficiency in diagnosing by reducing a contrast amount and an exposure dose. SOLUTION: A main scanning condition is set, so as to perform an inspection on the blood circulation of a subject with a contrast injected thereto by first scanning for scanning by supplying the tube current of a first tube current value A1 to an X-ray tube 20 and to perform imaging on the blood vessel of the subject with the contrast injected thereto by by second scanning for scanning by supplying a second tube current value A2 to the X-ray tube 20. Then the image of the subject is generated, based on projection data which is obtained by scanning the subject in response to the main scanning condition. COPYRIGHT: (C)2007,JPO&INPIT
