发明名称 MAGNETIC RESONANCE IMAGING APPARATUS AND METHOD
摘要 A magnetic resonance imaging apparatus comprising static magnetic field generating means for generating a static magnetic field in an imaging space, measuring means for generating a high-frequency magnetic field and a gradient magnetic field in the imaging space and measuring a nuclear magnetic resonance signal generated from an object to be examined placed in the imaging space, signal processing means for reconstructing a magnetic resonance image according to the nuclear magnetic resonance signal, control means for controlling the measuring means and the signal processing means, and display means for displaying the reconstructed magnetic resonance image obtained by the signal processing means. The magnetic resonance imaging apparatus further comprises storing means for storing a first set of information representing an inhomogeneous distribution of the static magnetic field generated depending on the characteristic of the static magnetic field generating means and a second set of information representing an inhomogeneous distribution of the static magnetic field generated depending on the tissue of the object, setting means for setting a field of view for imaging in a desired region of the object, selecting means for selecting information corresponding to the set field of view for imaging out of the second set of information as a third set of information, and correcting magnetic field generating means for generating a correcting magnetic field according to the third set of information and the first set of the information.
