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.
