摘要

#CMT# #/CMT# The detuning device (1) comprises a detuning component (4), which is switchable between a detuning state and a receiving state by a continuous switching signal. A control device (10) is provided for switching a switching device (7) and for generating the switching signals. Diplexers (14) are provided upstream to the switching device for the dynamic switching coil elements (3) and the detuning component for each coil element for switching the detuning component into the detuning state when the switching signal is absent. #CMT#USE : #/CMT# Detuning device for a receiving coil with multiple coil elements for a magnetic resonance device (Claimed) for use in magnetic resonance imaging. #CMT#ADVANTAGE : #/CMT# The diplexers are provided upstream to the switching device for the dynamic switching coil element and the detuning component for each coil element for switching the detuning component into the detuning state when the switching signal is absent, and thus reduces complexity of the detuning device, particularly in terms of wiring and control effort, and ensures a simple structure of the detuning device, and also enables efficient switching of the current or voltage source into a state of reduced current flow if the selected coil elements are not received, and ensures efficient detuning of the receiving coil. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a detuning device. 1 : Detuning device 2 : Receiving coil 3 : Coil element 4 : Detuning component 7 : Switching device 10 : Control device 14 : Diplexer.
