ABSTRACT:
An object of the present invention is to perform multiple slice imaging accompanied by saturation irrespective of the inhomogeneity of static magnetic field strength. An error of a peak resonant frequency of spins at each slice position is measured. A maximum value is extracted from among errors of peak resonant frequencies of spins in all slices relative to a center frequency with the peak resonant frequency of spins in water between the center frequency and the peak resonant frequency of spins in fat. Spins are excited at a frequency that deviates from the center frequency towards the peak resonant frequency of spins in water by a value calculated by adding the maximum value to a theoretical change in a peak resonant frequency stemming from a chemical shift.
