US Patent 12059286 Radiography apparatus

A radiography apparatus includes a drive circuit that drives a radiation source, an internal power supply that makes a current flow to the drive circuit at a first voltage, an external power supply that makes a current flow to the drive circuit at a second voltage different from the first voltage, a power feed controller that performs power feed to the drive circuit using at least one of the internal power supply or the external power supply, and a radiation output restriction unit that controls an output of radiation by a power supply to be used in the power feed to the drive circuit by the power feed controller.
