Abstract
A decoupling circuit for decoupling an local coil during the application of an RF excitation signal in a magnetic resonance imaging system includes a passive switching circuit for switching an inductor in parallel with a capacitive circuit in the local coil, and a discharge circuit for discharging residual currents from the circuit, therefore allowing for rapid coupling and decoupling of the local coil.
