Abstract

A local coil facility is disclosed for a magnetic resonance tomography apparatus for examining an examination object. In at least one embodiment, the local coil facility includes at least one electronic processing system, a high frequency antenna, and an antenna housing to cover the high-frequency antenna and the at least one electronic processing system, the antenna housing having at least one wall close to the object and at least one wall away from the object. To reduce or even minimize the attenuation of PET radiation in a combined MR/PET device and thus in particular to ensure a better signal to noise ratio for the PET measurement, it is proposed according to at least one embodiment of the invention that the surfaces of the wall away from the object are essentially tangential to the examination object.
