<P>PROBLEM TO BE SOLVED: To obtain a multi-array coil (MAC) summation effect with high accuracy in short time even though a phase characteristic distribution of respective coils has a spatial non-uniformity, i.e., to prevent the reduction of SNR due to the non-uniformity of phase characteristics, in MRSI measurement using a magnetic resonance imaging apparatus provided with a MAC. <P>SOLUTION: Using a non-water-suppressed image signal with high SNR, obtained in non-water-suppressed measurement (reference measurement) without water suppression, a correction value for correcting the phase distortion is calculated on each pixel in each coil. After correcting a phase on each pixel in each coil of a main-scan image signal measured under suppressing water (water-suppressed image signal) using the corrective value, the adding operation (summation) of an image to be generated in each coil is performed. Then, normal phase correction is performed on a summed spectrum signal. <P>COPYRIGHT: (C)2012,JPO&INPIT |
