Abstract
A nuclear magnetic resonance imaging apparatus in which a synchronizing signal is generated from a periodic physiological signal generated by a subject to be inspected, and a radiofrequency burst pulse is applied to the subject to be inspected in synchronism with the synchronizing signal while a gradient magnetic field in one direction is being applied to the subject to be inspected to modulate nuclear magnetizations of the subject to be inspected in the one direction. The radiofrequency burst pulse includes plural sub-pulses which are formed at equidistant intervals on a time axis and which have amplitudes modulated by a sinc function.
