ABSTRACT:
A method and an apparatus for heart beat synchronous nuclear magnetic resonance imaging capable of improving the quality of the nuclear magnetic resonance images synchronous with the heart beat by reducing erroneous generation of synchronization signals due to noises in the electro-cardiographic waves. In the apparatus, noises are removed from the electro-cardiographic waves obtained from the patient; synchronization signals are generated in correspondence to the noise removed electro-cardiographic waves; and nuclear magnetic resonance images are taken by collecting nuclear magnetic resonance signals from the patient at collection timings determined in correspondence to the synchronization signals, and by reconstructing the nuclear magnetic resonance images by using the collected nuclear magnetic resonance signals.
