Abstract

A shielding for a magnetic resonance tomography device, in the form of a shell of a cylinder, for arrangement radially between a radially outer gradient coil system for generating a magnetic field gradient in an examination space of the MRT device and a radially inner RF coil system for sending and/or receiving RF signals into the examination space and from the examination space, is provided. The shielding includes strips that are arranged on a shielding surface, are electrically conductive and are separated from one another by slits. The strips have respectively angled and/or rounded profile segments to create a two-dimensional pattern of shielding rings on the shielding surface.
