METHOD AND DEVICE FOR PRODUCING MAGNETIC RESONANCE ELASTOGRAM (MRE), AND BALL VIBRATOR FOR PRODUCING MAGNETIC RESONANCE ELASTOGRAM (MRE)

摘要

PROBLEM TO BE SOLVED: To enable a magnetic resonance elastogram (MRE) using a magnetic resonance imaging equipment (MRI) to be produced by a sufficient alternate stress. SOLUTION: A ball vibrator which generates vibration resulting from a centrifugal force accompanying rotation of a non-magnetic ball in the circumferential direction around the central point is arranged in a manner to come into contact with a predetermined part of an object of which image is to be formed. Then, a magnetic resonance elastogram (MRE) pulse sequence is applied to the object, and the vibration from the ball vibrator is loaded to produce the magnetic resonance elastogram (MRE).
