ABSTRACT:
In a nuclear magnetic resonance (NMR) diagnostic apparatus, the NMR signals from a portion of an object excited repeatedly by the same type excitation pulses are temporarily stored and the signal-to-noise (S/N) ratio thereof is improved by summing together at least two cos signal components, or two sin signal components of the NMR signals which were taken during these examination periods. An image processing circuit is used to process the NMR signals with impioned S/N ratio so as to obtain a tomographic image of the object.
