A patient couch is disclosed, for a combination of positron emission tomography and magnetic resonance tomography device (PET/MRT device), for presenting images of an examination object in an examination room. A system, including the patient couch and a combination of positron emission tomography and magnetic resonance tomography device, is also disclosed. In an embodiment, the patient couch includes a reclining surface for a patient, which is designed to only insignificantly attenuate radiation intensity originating from a positron decay when it passes therethrough.
