<;P>;PROBLEM TO BE SOLVED: To sufficiently show the performance of an apparatus, while securing safety in the subject. <;P>;SOLUTION: Laser radiation parts 15a-15f are respectively arranged in a gantry so as to allow a laser to be radiated to any place inside the opening of the gantry. A simulation part 86a generates simulation data where dB/dt to be generated in the respective places inside the opening of the gantry is associated with spatial positions inside the opening according to the imaging condition of a magnetic resonance image of the subject, and stores the generated simulation data in a simulation data storage part 84a. A laser radiation control part 86b performs control to radiate lasers from the laser radiation parts 15a-15f to the places where the dB/dt is a reference value or more while referring to the simulation data in a state where the subject is moved into the opening of the gantry in order to image the magnetic resonance image. <;P>;COPYRIGHT: (C)2011,JPO&INPIT
