Abstract
In a nuclear magnetic resonance tomography apparatus, having a high-frequency excitation and measuring coil connected with a capacitor to form a resonant circuit, the capacitor being tuned to a desired operating frequency, a circuit is provided for limiting the voltage of the resonant capacitor in a transmission mode. Avoidance of impermissible peak amplitudes is thereby achieved without the necessity of over-dimensioning the components of the resonant circuit.
