摘要： An X-ray generating apparatus controls driving of an X-ray tube. The X-ray tube includes an electron source emitting electrons due to application of a voltage, a transmission-type target generating an X-ray due to collision of electrons emitted from the electron source, and a shield member disposed between the electron source and the transmission-type target, the shield member having an opening that electrons emitted from the electron source pass through, and blocking an X-ray that scatters toward the electron source. When generating the X-ray, application of a voltage to the transmission-type target is started, and emission of electrons from the electron source is caused after passage of a predetermined period indicating a time period from starting voltage application until the transmission-type target reaches a predetermined voltage. When stopping X-ray generation, application of the voltage to the transmission-type target is stopped after stopping the emission of electrons from the electron source.
