Magnetic resonance imaging method and apparatus.

摘要

In order to narrow the dynamic range of an NMR signal and to provide MRI of low cost and high image quality without inducing image distortions or degradations of the measurement accuracies of various parameters, a coil (104) for generating an inhomogeneous magnetic field which varies slowly within the region to-be-imaged is provided in addition to a coil (101) for generating a static magnetic field of high homogeneity, and the current flowing through the former coil (104) is changed so as to control the inhomogeneous magnetic field.
