Imaging support device, and operation method and operation program for the same

An operation method for an imaging support device used in a radiography apparatus including a radiation source and a radiation image detector that detects a radiation image of a subject on the basis of radiation emitted from the radiation source and transmitted through the subject, the imaging support device including an optical camera that optically images a region including an irradiation field of the radiation applied to the subject from the radiation source, the operation method comprising:

• acquiring an optical image indicating the subject in the region by causing the optical camera to perform imaging in conjunction with radiography performed by the radiography apparatus;
• storing a radiation image acquired through the radiography and the optical image in a storage device in association with each other;
• acquiring, as a second optical image, an optical image indicating the subject in the region by causing the optical camera to perform imaging after the radiography is performed;
• and
• displaying a superimposition image, in which the first optical image and the second optical image are superimposed, and the radiation image on the display unit.

A non-transitory computer-readable storage medium storing an operation program for operating an imaging support device used in a radiography apparatus including a radiation source and a radiation image detector that detects a radiation image of a subject on the basis of radiation emitted from the radiation source and transmitted through the subject, the imaging support device including an optical camera that optically images a region including an irradiation field of the radiation applied to the subject from the radiation source and at least one processor, the operation program causing the processor to execute:

• an operation of acquiring an optical image indicating the subject in the region by causing the optical camera to perform imaging in conjunction with radiography performed by the radiography apparatus;
• an operation of storing a radiation image acquired through the radiography and the optical image in a storage device in association with each other;
• an operation of acquiring, as a second optical image, an optical image indicating the subject in the region by causing the optical camera to perform imaging after the radiography is performed;
• and
• an operation of displaying a superimposition image, in which the first optical image and the second optical image are superimposed, and the radiation image on the display unit.
