ABSTRACT:
Nuclear magnetic resonance diagnostic apparatus including a magnet for generating a uniform static magnetic field, a first coil for generating a gradient magnetic field, a selective detector for detecting the free induction decay signals from the selective slice portion of an object, a current controller for controlling the current in the first coil to the shift the selective slice portion, a second coil for generating the gradient magnetic field direction in the selective plane of the object, a projection data producer for obtaining a one-directional projection data on the basis of the detected free induction signals, and an image synthesizer for producing the extensive one-directional projection of the specified atomic nuclei distribution in the object by placing a plurality of one-directional projection data.
