Abstract
An NMR diagnostic apparatus capable of obtaining tomographic images in any direction and in any portion of the patient. A magnetic device applies a static magnetic field along a longitudinal axis of the patient. A first coil device is arranged along this longitudinal axis and applies a first gradient magnetic field in conjunction with the static magnetic field so as to define a slice in the patient which is to be examined. The first coil device also applies at least one second gradient magnetic field which defines a projection angle from which NMR signals are obtained. A probe head coil device applies RF pulses to excite nuclei in the slice and to detect the NMR signals emanating from the slice. A second coil device is arranged along the longitudinal axis and applies to the slice a shifting magnetic field which shifts a magnetically-zero plane of the first gradient magnetic field in a direction perpendicular to the magnetically-zero plane. A plurality of second coil means may be provided to shift a magnetically-zero plane throughout the patient so that slices in any portion of the patient may be examined.
