Abstract: A magnetic resonance apparatus includes a patient couch with a couch surface on which a patient is supportable. In the patient couch, lower local coils for receiving excited magnetic resonance signals of the patient are arranged below the couch surface. On an upper side of the patient couch, connecting devices are arranged to sides. The magnetic resonance device includes upper local coils that are detachably connected mechanically and electrically with the connecting devices. The lower local coils and the upper local coils are connected to electronics that at least include a respective pre-amplifier and are connected via connection lines arranged outside the patient couch to an evaluation device. In a state in which the upper local coils are connected to the connecting devices, the upper local coils are fixed mechanically to the patient couch and cover the patient in a dome shape. The electronics are arranged in the patient couch.

Abstract: A support unit is disclosed for positioning a patient within a medical imaging apparatus with at least one magnetic resonance device; along with a patient positioning apparatus and a medical imaging apparatus including such a support unit. In an embodiment, the support unit includes at least one bearing element for movable positioning relative to a patient positioning apparatus and a coil unit for receiving magnetic resonance raw data. The coil unit includes a flat supporting surface for positioning the patient.

Abstract: A method, a computer program product and a computer readable storage medium are disclosed for generating a global attenuation map used for attenuation correction of positron emission tomography image data sets in a combined magnetic resonance-positron emission tomography device. In an embodiment, during the course of detecting hardware components of the combined magnetic resonance-positron emission tomography device and determining positions of the detected hardware components relative to a patient support, the global attenuation map is generated as a function of the detected hardware components.
