PROBLEM TO BE SOLVED: To provide an art for obtaining high-quality images at high speed in DKI analysis.SOLUTION: In DKI analysis, least-square fitting and constraint processing are separated from each other when estimating parameters relating to dispersion of MPG pulses in every application direction, and correction processing only with respect to a pixel value of the pixel becoming out of range of a constraint condition in the least-square fitting is performed. With respect to the pixel, parameters relating to the dispersion is estimated again from the pixel value after correction, and a parameter image using the obtained parameter relating to dispersion is generated. |
