Abstract

An NMR imaging apparatus which generates NMR signals cleared of foreign noises by adding a noise detecting coil, for detecting mainly the foreign noises, to an intrinsic detecting coil for detecting the NMR signals and by producing a difference from the outputs of the two detecting coils. As a result, the foreign noises can be eliminated simply and effectively without requiring expensive shielded rooms.
