PROBLEM TO BE SOLVED: To pick up an image for a short time while using an SSFP pulse sequence in which RF excitation is accomplished by a phase cycling method. SOLUTION: Data regarding all the frequency domains are collected by a first phase system, data regarding low frequency domains are collected respectively by a plurality of remaining phase systems, data regarding all the frequency domains are separated into data of the low frequency domains and data of high frequency domains, 0 data are added to the data of the low frequency domains, 0 data are added to the data of the high frequency domains, 0 data are added to data of the low frequency domains collected respectively by the remaining plurality of phase systems, low space frequency images based on the data of the respective low frequency domains to which 0 is added are reconstructed respectively, high spatial frequency images based on the data of high frequency domains to which 0 is added are reconstructed, and high spatial frequency images, and the respective low spatial frequency images and a scaling factor are multiplied are all added up.
