Abstract
A head antenna for nuclear magnetic resonance examinations has an examination chamber, formed so as to accept the head, and an antenna conductor, formed as a frame antenna, that surrounds the examination chamber in an examination position. The antenna conductor is divided into two curved sub-conductors that respectively have electrical contacts at their ends for detachably electrically connecting the sub-contractors together. The first sub-conductor arrangement is fastened to a holding part which is arranged outside the examination chamber and which is made of an electrically non-conductive, non-ferromagnetic material. For fastening the holding part to a patient support, a first fastening assembly is arranged on the holding part. For fixing the position of the head, a second fastening assembly is arranged on the holding part.
