MAGNETIC RESONANCE IMAGING APPARATUS AND METHOD FOR MEASURING FREQUENCY SHIFT

摘要

A magnetic resonance imaging apparatus according to an embodiment of the present invention is provided with a phase-image-generating unit (42) for generating a first phase image by carrying out a sequence for applying a bipolar gradient magnetic field pulse, an image-value-obtaining unit (43) for obtaining the image value of the first phase image, and a frequency-shift-calculating unit (44) for finding the frequency shift per unit gradient magnetic field on the basis of the image value of the first phase image and on the magnetic field intensity of the bipolar gradient magnetic field pulse.
