Abstract
A magnetic resonance imaging apparatus includes a magnetic field generation means for applying gradient magnetic fields and a radio-frequency magnetic field to a patient placed in a static magnetic field in a predetermined pulse sequence; a multiple RF receiving coil comprising at least three RF receiving coils for receiving the nuclear magnetic resonance signals generated from the patient; and an image reconstruction means for reconstructing an image by processing the received nuclear magnetic resonance signals, wherein the image reconstruction means includes a coil selection means for selecting a plurality of RF receiving coil groups that are preset by combining the plurality of RF receiving coils according to imaging conditions, a synthesization means for synthesizing the measured data received by the respective RF receiving coils of each of the plurality of selected RF receiving coil groups, and a calculation means for eliminating aliasing artifacts by executing a matrix calculation as to the synthesized data.
