Claim of US Patent No. 10,768,258

1. A magnetic resonance imaging apparatus, comprisingprocessing circuitry configured to
perform at least one of first data collection and second data collection, wherein the first data collection collects a plurality of first data by collecting data of an imaging region of a subject at a plurality of different times with predetermined time intervals after a tag pulse is applied to fluid flowing into the imaging region, and the second data collection collects a plurality of second data by collecting data of the imaging region at a plurality of different times with the predetermined time intervals by differing at least one of application or non-application of the tag pulse and a position of the applying in the first data collection; and
generate a plurality of first images respectively corresponding to a plurality of particular times of the plurality of different times from at least one of the first and second data collected at the particular times by performing phase correction for the at least one of the first and second data collected at the particular times, using phase data included in the first or second data, wherein the phase data is data collected at a timing when a longitudinal magnetization of the fluid is a positive value, and collected at a time other than the particular times.
