1. A radiography system comprising:
a radiation generation device including a radiation source unit that emits radiation;
a projector that projects an image in an emission direction of the radiation; and
at least one processor,
wherein the at least one processor
acquires distance information indicating a distance from the radiation source unit to a projection surface on which the image is projected,
acquires a subject image which is a radiation image captured in the past for a subject of the radiation image,
derives, based on the distance information, a visualization range of the subject visualized in the radiation image, which is captured for the subject and is based on the radiation emitted from the radiation source unit,
trims the subject image based on the visualization range, and
causes the projector to project the trimmed subject image.
