Nuclear magnetic resonance diagnostic apparatus.

摘要

In an NMR diagnostic apparatus (100), a plurality of tomographic images in the diseased portion of the patient (P) are desirable to obtain diagnostic information thereof. To obtain a plurality of tomographic images, an auiliary coil (20) as a gradient field shifting coil is provided adjacent to the gradient field coils (19) in such a manner that combined magnetic field (GR; GS) generated by the auxilary coil (20) and the gradient field coils (19) serves to shift a magnetically-zero plane where the NMR phenomenon occurs under the influence of the static field (H0) and the RF pulse (H1).
