<P>PROBLEM TO BE SOLVED: To provide a simultaneous and continuous measurement system of brain waves and brain function measurement (called functional MRI or fMRI) for performing fMRI by using a magnetic resonance imaging (MRI) apparatus which is a medical image diagnostic apparatus and measuring the brain waves as a biological phenomenon simultaneously with the brain function measurement. <P>SOLUTION: The simultaneous and continuous measurement system of the brain waves and the fMRI is provided with a brain wave measuring apparatus for measuring the brain waves and an fMRI apparatus for measuring brain functions by magnetic resonance imaging. Brain wave sampling pulses are generated such that the waveform of an image artifact in gradient magnetic field change for gathering fMRI data in the fMRI apparatus is on a baseline at the sampling timing of gathering brain wave data in the brain wave measuring apparatus on the basis of the clock function of the fMRI apparatus. <P>COPYRIGHT: (C)2006,JPO&NCIPI
