1. A power supply circuit for a computed tomography system, the power supply circuit comprising:
a stationary power distributor including an uninterruptible power supply;
a co-rotating bias voltage supply, the co-rotating bias voltage supply including,
a voltage supply input,
a bias voltage supply output, and
a bias voltage monitoring unit, the bias voltage monitoring unit being configured to activate or to deactivate the bias voltage supply output as a function of an electrical input voltage detected at the voltage supply input, and the bias voltage monitoring unit includes a sensor configured to detect the electrical input voltage at the voltage supply input; and
an auxiliary voltage source having a power buffer, the power buffer configured to supply the bias voltage monitoring unit with electrical power for deactivation of the bias voltage supply output.
