Abstract
Controlling unit for a radiation source includes a mains-driven power supply terminal connectable to a mains-driven power supply, a battery-driven power supply terminal connectable to a battery-driven power supply, a failsafe power supply terminal, a processor unit to control the radiation source, and a patient-in-place sensor unit to provide a respective signal to the processor unit. The failsafe power supply terminal is connected to the mains-driven power supply terminal via a first diode and to the battery-driven power supply terminal via a second diode and he processor unit is connected to the failsafe power supply terminal to receive power from the higher voltage power supply terminal of the mains-driven power supply terminal and the battery-driven power supply terminal, respectively. The processor unit is adapted to shut down the radiation source in case a patient-not-in-place signal is provided.
