Abstract: 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.

Abstract: 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.

Abstract: An information processing apparatus comprising at least one processor, wherein the processor is configured to: acquire at least one optical image obtained by optically imaging a subject; acquire at least one radiation image obtained by radiography of the subject from a direction substantially the same as an imaging direction of the optical imaging; estimate a position of at least one first region of interest based on the optical image; and specify a second region of interest corresponding to the position of the first region of interest in the radiation image.

Abstract: 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.

Abstract: An information processing apparatus comprising at least one processor, wherein the processor is configured to: acquire at least one optical image obtained by optically imaging a subject from a first direction; estimate a position of at least one first region of interest based on the optical image; acquire a plurality of radiation images obtained by continuously performing radiography of a state in which the subject swallows a sample from the first direction; specify a second region of interest corresponding to the position of the first region of interest in the radiation image; monitor a position of the sample based on the plurality of radiation images; and change an imaging condition for the radiography based on a positional relationship between the second region of interest and the sample.

Abstract: 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.
