1. A medical data processing apparatus comprising processing circuitry configured to:
acquire a plurality of pieces of imaging data acquired by executing spoiled gradient echo imaging and coherent gradient echo imaging by using a plurality of flip angles;
generate a low-rank approximate image set, which is a set of low-rank approximated images, from the imaging data; and
reconstruct one or more parameter maps using the low-rank approximate image set and a multi-pool model related to water exchange in a biological tissue, the multi-pool model including plural free waters and bound water that performs magnetization exchange with the free waters.
