Abstract
A magnetic resonance apparatus with a radio-frequency shield at a reference potential, a detuning circuit and an electrical line which is connected with the detuning circuit. The electrical line is fashioned as a strip conductor and is attached to the radio-frequency shield. The strip conductor can be used for direct current/direct voltage supply of the detuning circuit. This has the advantage that the detuning circuit can be activated without exerting a significant interfering influence on the magnetic field in the magnetic resonance apparatus.
Claims8
A magnetic resonance apparatus comprising;
- a radio-frequency resonator;
- a radio-frequency shield at a reference potential;
- a voltage source providing a voltage with respect to said reference potential;
- a strip conductor connected to said voltage source and attached to said radio-frequency shield;
- and
- a detuning circuit connected to said radio-frequency resonator for selectively detuning said radio-frequency resonator, said detuning circuit being electrically connected to said radio-frequency shield and to said strip conductor.
