ABSTRACT:
A nuclear magnetic resonance tomography apparatus includes a Faraday cage which shields the measurement space against stray electromagnetic fields, and increases the Q factor of a coil circuit comprising the transmitting/receiving coils of the apparatus. This Faraday cage is arranged around the object space inside the magnetic coils for generating the necessary steady magnetic field, but around and outside the RF transmitting/receiving coil. The transmitting/receiving coil may be provided with comb-like screens which shield against electrical fields, and the Faraday cage may include a readily accessible extension having larger transverse dimensions.
