In order to do so, in imaging of an object performed by combination of a plurality of pulse sequences, a SAR graph showing a temporal change in the predicted SAR value of each pulse sequence is displayed. When the predicted SAR value of the pulse sequence is the same as or exceeds the upper SAR limit, the exchange of such pulse sequences or the insertion of a waiting time is performed.
