MAGNETIC RESONANCE IMAGING DEVICE AND MAGNETIC RESONANCE IMAGING METHOD

摘要

A magnetic resonance imaging device is provided with a static magnetic field magnet, an inclined magnetic field coil, a high frequency coil, an image reconstruction unit, a correction information memory unit and an image processing unit. The static magnetic field magnet generates a static magnetic field. The inclined magnetic field coil applies an inclined magnetic field to be overlapped with the static magnetic field to an examinee. The high frequency coil receives a magnetic resonance signal generated from the examinee. The image reconstruction unit generates a reconstruction image in a reconstruction FOV (field of view) of the examinee in accordance with the magnetic resonance signal. The correction information memory unit stores correction information on position coordinates makes position information in the reconstruction FOV and position information in a display FOV included in the reconstruction FOV to correspond to each other in accordance with the inclined magnetic field. The correction information is information to make only first position coordinates correspond to the position coordinates in the display FOV in the case where the first position coordinates close to the center of the reconstruction FOV and second position coordinates far from the center of the reconstruction FOV correspond to the position coordinates in the display FOV. The image processing unit carries out correction processing of the reconstruction image in accordance with the correction information to obtain the image in the display FOV.
