Abstract
Radio frequency pulses are repeatedly applied to a sample including a fluid portion positioned in a static magnetic field, so that spins of the sample are put into the steady-state free precession state so as to generate an FID signal just after the radio frequency pulse and generate a time-reversed FID signal just before the next radio frequency pulse. Both of the signals generated thus are detected and are subjected to image reconstruction process to image the fluid portion of the sample.
