Magnetic resonance imaging apparatus and method

摘要

A magnetic resonance imaging apparatus comprises: magnetic field generation means (403, 404) for applying gradient magnetic fields (602 to 604) and a radio-frequency magnetic field (601) to a patient (401) placed in a static magnetic field in a predetermined pulse sequence; a multiple RF receiving coil (412) comprising a plurality of first RF receiving coils (4051 to 4058) for receiving the nuclear magnetic resonance signals (606) generated from the patient (401); and image reconstruction means (407, 411) for reconstructing an image by processing the received nuclear magnetic resonance signals (606), wherein the image reconstruction means (407, 411) comprises: coil selection means for selecting a plurality of RF receiving coil groups that are preset by combining the plurality of first RF receiving coils (4051 to 4058) according to imaging conditions; and synthesization means (415) for synthesizing the measured data received by the respective first RF receiving coils (4051 to 4058) of each of the plurality of selected RF receiving coil groups and calculation means for eliminating aliasing artifacts by executing a matrix calculation as to the synthesized data.
