A ball vibrator that generates vibrations caused by a centrifugal force along with the rotation of a nonmagnetic ball around the center point in the circumferential direction is disposed so as to come into contact with a predetermined part of an object, an image of which is to be formed. Then, a magnetic resonance elastogram (MRE) pulse sequence is applied to the object, and a magnetic resonance elastogram (MRE) is created by using the vibrations from the ball vibrator.
