A method for controlling an x-ray radiation emitting device comprising an x-ray radiation source that emits x-ray radiation to an imaging target, a collimator that sets an x-ray radiation field region, a visible light source that emits visible light, a stop that is disposed separately from the collimator and that matches an irradiation range of the visible light on the imaging target with the x-ray radiation field region, camera for capturing an image of the imaging target, a display unit that displays the image captured by the camera, and a single switch that drives the visible light source, the method comprising:
- issuing a collimator driving command to direct the collimator to set the x-ray radiation field region determined from the captured image displayed by the display unit to the collimator in a case in which the single switch is operated.
