ABSTRACT:
A nuclear magnetic resonance imaging system divides a measurement space, which is a time band in which measurement signals are generated, into a plurality of partial regions, and measures data under the application of the corresponding gradient magnetic fields to the partial regions so that signals for a blood stream part have their phase consistent at the measurement time point for each partial region. The system synthesizes the data in each partial region, thereby producing image data consisting of only the data with a consistent phase over the entire measurement space, and extracts only the image data for the blood stream part by cancelling image data for a quiescent part from the image data synthesized.
