The examination couch 15 also has a support region 39 for supporting and/or positioning the patient 13, wherein the support region 39 is arranged on the examination couch 15 between the two lateral edge regions 37, 38. The two plug contacts 29, 30 arranged at opposite lateral edge regions 37, 38 of the examination table 15 form a local radio frequency coil 27 for contacting the flexibility.
The fourth plug-in contact 31 of the four plug-in contacts 28, 29, 30, 31 arranged on the examination couch 15 is arranged in the rear half of the examination couch 15 in the longitudinal direction 40 of the examination couch 15. The fourth plug contact 31 is likewise designed as a direct contact which, when in contact with the local radio frequency coil 27, simultaneously brings about a mechanical positioning of the local radio frequency coil 27, in particular of the fixed local radio frequency coil 27, in terms of data exchange and/or energy supply between the local radio frequency coil 27 and the plug contact 31.
The examination couch 15 also has a second mechanical plug element 41, which is arranged on the examination couch 15 beside a fourth plug contact 31 arranged in the rear half of the examination couch 15. In this case, not only the fourth plug contact 31 but also the second mechanical plug element 41 are arranged next to one another in the rear half of the examination table 15. The second mechanical plug element 41 serves to stabilize the position of the local radio frequency coil 27 connected and/or plugged at the fourth plug contact 31 in order to prevent an asymmetrical force distribution and/or undesired rotation of the local radio frequency coil 27.
