摘要：
With the object of enhancing image quality, a transmission sensitivity distribution calculating part calculates a transmission sensitivity distribution by a double flip angle method. Next, a threshold processing part threshold-processes the calculated transmission sensitivity distribution. Further, an image correcting unit corrects an actual scan image using the transmission sensitivity distribution subsequent to the threshold processing.
