System and method for electrically contacting local coils with a signal processor remote therefrom in a magnetic resonance scanner
First Claim
1. A magnetic resonance apparatus comprising:
- a magnetic resonance data acquisition unit configured to acquire magnetic resonance data from an examination subject interacting with the magnetic resonance data acquisition unit;
a plurality of local coils in said magnetic resonance data acquisition unit that participate in said acquisition of magnetic resonance data by transmitting radio frequency signals into, and/or receiving magnetic resonance signals from, the examination subject;
each of said magnetic resonance local coils having a coil coupler element electrically connected thereto and mounted in said magnetic resonance data acquisition unit;
a signal processor in said magnetic resonance data acquisition unit remote from said local coils;
a plurality of apparatus coupler elements mounted in said magnetic resonance data acquisition unit that are electrically connected to said signal processing unit;
a moveable element, on which said local coils are carried, that moves in a movement path in said magnetic resonance data acquisition unit; and
said coil coupler elements being disposed on said moveable element, and said apparatus coupler elements being disposed in said magnetic resonance data acquisition unit, to cause at least some of said coil coupler elements to successively couple, for signal transmission, at least some of said apparatus coupler elements at least within a segment of said movement path.

Abstract
In a contacting system and method for contacting magnetic resonance local coils with a unit for additional signal processing of a magnetic resonance data acquisition unit, a number of coil coupler elements are electrically connected with the magnetic resonance local coils and apparatus coupler elements are mounted at the magnetic resonance tomograph, and are electrically connected with a unit for signal processing. The coil coupler elements and the apparatus coupler elements are fashioned so that, given a movement of the local coils along a movement path in the magnetic resonance data acquisition unit, a successive contacting of at least a portion of the coil coupler elements with apparatus coupler elements ensues at least over a specific path segment of the movement.
