Abstract
To provide a control device, a method, and a program for a radiation imaging apparatus, capable of appropriately setting a parameter in imaging according to a region of a subject.SOLUTION: When controlling a radiation imaging apparatus including a photon counting type detector that detects radiation emitted from a radiation source and transmitted through a subject on a bed and outputs a detection signal corresponding to photon energy of the radiation, a highly sensitive site having relatively higher sensitivity to the radiation in the subject than other sites is specified based on an optical image acquired by a camera that acquires the optical image of the subject, and different parameters related to a radiation dose to be emitted to the subject are set for the highly sensitive site and the other sites.SELECTED DRAWING: Figure 3
