ABSTRACT:
A tomography apparatus utilizing nuclear magnetic resonance techniques for representing internal cross-sections of an examination subject has a surface coil for acquiring a signal corresponding to the displacement of the nuclear spins of the examination subject from a equilibrium position. The surface coil is annular and has its ends connected to ground through respective capacitances. A tape-shaped high-frequency shielding at least partially surrounds the surface coil.
