MAGNETIC RESONANCE IMAGING APPARATUS AND SAR COMPUTING METHOD

摘要

A magnetic resonance imaging apparatus includes a static magnetic field generator, a gradient magnetic field generator, a transmission coil and a processing circuitry. The static magnetic field generator generates a static magnetic field. The gradient magnetic field generator generates a gradient magnetic field. The transmission coil applies an RF pulse to an object. The processing circuitry determines high frequency pulse power absorbed by other than the object in accordance with a volume of the object and computes a specific absorption rate (SAR) with the determined high frequency pulse power.
