<P>PROBLEM TO BE SOLVED: To diagnostic-read an aspect of a brain function activation portion varied with time. <P>SOLUTION: An image generation control part 86b controls a functional image generating part 82b, to generate fMRI images of respective statistical processing blocks, by statistical-processing a plurality of magnetic resonance images along the time-series generated by an image generating part 82a, in every statistical processing block, when the statistical processing blocks are set to divide the plurality of magnetic resonance images generated along the time-series in a period with rest and tasks repeatedly a plurality of times along the time-serial line, into image groups of distributing a rest time and task time adjacent along the time-series, as a basic blocks. A display control part 86c controls the fMRI images of the respective statistical processing blocks generated by the functional image generating part 82b to be displayed on a monitor of a display part 85. <P>COPYRIGHT: (C)2011,JPO&INPIT
