To provide a means by which the relationship between time interval of trigger signals and timing of measurement terms to the value of a set imaging parameter is easily found out in synchronous measurement.

The means includes a magnetostatic field generator for generating a magnetostatic field; a biosignal catching means for catching a biosignal from a subject positioned in the magnetostatic field, a synchronous measurement means for controlling the measurement of nuclear magnetic resonance signals from the subject the set imaging parameter in such a way that the nuclear magnetic resonance signals may synchronize with the trigger signals based on the biosignals, a means for reconstructing an image from nuclear magnetic resonance signals of the subject, and a displaying means for displaying the image, wherein the displaying means displays the display showing the biosignals and the display showing measurement terms of synchronous measurement in such a way that they may correspond to each other in a temporal positional relation.
