A plug connection device that connects two function elements for signal and power transmission between the function elements, in particular for medical applications, has connection components fashioned for capacitive connection of the function elements.

Plug connection device designed to connect two function elements for signal and power transmission

An antenna array for magnetic resonance examinations has array elements that are decoupled from each other and that are independent, the array elements being arranged in two adjacent rows. Each array elements is formed by two antenna elements whose respective sensitivity axes reside perpendicular to one another.

Antenna array for magnetic resonance examinations

A circularly polarizing local antenna for use in a magnetic resonance apparatus is formed by first and second antennae, which are in turn respectively formed by first and second coils. The second coil has an opening surrounding an examination region, through which an examination subject can be introduced. The arrangement includes a coil holder, to which the first coil is attached so as to be movable between first and second positions and to which the second coil is rigidly attached. When the first coil is oriented in the first position, it also surrounds the examination region, with the respective coil axes of the first and second coils being disposed substantially perpendicular to each other. In the first position, the first coil obstructs the opening of the second coil. By moving the first coil from the first position to the second position, the first coil becomes oriented so as to leave the opening of the second coil unobstructed, permitting unimpeded introduction of the examination subject into the examination region.
