A CPU of a console includes a first acquisition unit, a second acquisition unit, a specifying unit, and an extraction unit. The first acquisition unit acquires designation information of a measurement target part of a bone density of a subject. The second acquisition unit acquires an optical image obtained by imaging the subject facing radiography with a camera. The specifying unit specifies a region of the measurement target part in the optical image based on the designation information. The extraction unit extracts a region in a radiation image corresponding to the region of the measurement target part as a measurement region of the bone density based on correspondence relationship information between pixels of the radiation image and pixels of the optical image.

Imaging support apparatus, operation method of imaging support apparatus, and operation program of imaging support apparatus, for reducing extra irradiation exposure of a subject

A radiography system includes a radiation source that emits radiation, an electronic cassette that receives the radiation and detects a radiographic image, a portable first retainer that holds the electronic cassette, a string that is attached to the first retainer, and a camera that images the string. The first retainer includes a lock portion and a movable portion as an inclination change mechanism that can change an inclination of the electronic cassette with respect to the radiation source. The string and the camera constitute a first detection mechanism that detects an inclination of the electronic cassette about an X-axis which intersects a Z-axis and is directed toward the radiation source in a case in which a radiation detection surface of the electronic cassette and the radiation source are disposed to face each other.

Radiography system

A first acquisition unit acquires an optical image in which both an electronic cassette in which a detection panel for detecting radiation is built in a portable housing and a subject facing radiography using the electronic cassette are shown, from a camera. A first demarcation unit demarcates a detection region of the radiation by the detection panel, the detection region being determined in accordance with a position of the electronic cassette, in the optical image. A second demarcation unit demarcates an imaging region which is a region to be imaged in the radiography, the imaging region being determined in accordance with a position of the subject, in the optical image. A display controller performs control of displaying a frame indicating the detection region and a frame indicating the imaging region on a touch panel display in a manner of being superimposed on the optical image.

Imaging support apparatus, operation method of imaging support apparatus, and operation program of imaging support apparatus

A radiography system includes a radiation source that irradiates a subject with radiation, a camera, and a console. The camera is provided in the radiation source. The camera images the subject irradiated with illumination light that is, light having uniform brightness, to output an optical image. A CPU of the console has a first acquisition unit and a derivation unit. The first acquisition unit acquires the optical image from the camera. The derivation unit derives spinal column shape information representing a shape of a spinal column of the subject based on the optical image.

Radiography system, method for operating radiography system, and operation program for radiography system

A radiography apparatus includes an upright imaging stand that is used for radiography on a subject, a camera as a detection sensor that immediately detects a state of the subject with respect to the upright imaging stand, a tablet terminal, and a reflective member. The tablet terminal displays a notification screen including an image output from the camera. The reflective member reflects the notification screen such that the subject facing the upright imaging stand visually recognizes the image.
