Abstract: A magnetic resonance system that has a magnet system that generates magnetic fields in an excitation region, allowing nuclei in an examination subject in the excitation region to be excited to emit a magnetic resonance signal. A reception antenna device with multiple local coils for reception of the magnetic resonance signals is arranged in proximity to the examination subject, and has a base part and an attachment part. The attachment part can be placed on the base part such that the examination subject is located between the base part and the attachment part (6). The multiple local coils are respectively connected with an evaluation device for evaluation of magnetic resonance signals. To simply and reliably couple the antenna devices to an evaluation device with optimally few electrical conductors being located in the excitation region, the multiple local coils in the attachment part are respectively connected with the evaluation device via a base coupling element that is arranged at a predetermined base part location on the base part and an attachment coupling element is arranged at a predetermined attachment part location on the attachment part. The magnetic resonance signal received by the local coil can be fed to the evaluation device via the attachment coupling element and the base coupling element and as long as the attachment part is placed on the base part.

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.
