Abstract: A position detection unit is disposed at an exposure position that is included in a camera image and a field of view of a camera and outputs a position signal indicating the position of a part of a peripheral portion of an electronic cassette. The calculation unit calculates an in-image cassette position which is the position of the electronic cassette in the camera image, on the basis of the position, direction, and size of the position detection unit in the camera image and the position signal. A composite image generation unit generates a composite image of the camera image and a cassette frame indicating the in-image cassette position. A display controller displays the composite image on a touch panel.

Abstract: A radiography apparatus includes an operation controller that invalidates an operation of a collimator using a first operating unit in a case where a radiation generation unit is present vertically downward relatively to a radiography unit, and validates the operation of the collimator using the first operating unit in a case where the radiation generation unit is present vertically upward relatively to the radiography unit.

Abstract: A detection unit of a CPU of a console detects the position of an electronic cassette and the position of an irradiation field on the basis of a camera image output from a camera that is attached to an X-ray source and captures an image of at least the electronic cassette. The image processing unit performs image processing for an X-ray image detected by the electronic cassette on the basis of information of the position of the electronic cassette and information of the position of the irradiation field.

Abstract: A composite image generation unit of a CPU of a console combines a camera image obtained by capturing an image of a subject located in an irradiation field using a camera and a positioning index image indicating a set position of the subject, which has been set in advance with respect to an in-image cassette position that is the position of the electronic cassette in the camera image, to generate a composite image. In a case in which the in-image cassette position is changed with the movement of the electronic cassette, the composite image generation unit changes a display position of the positioning index image with the change in the in-image cassette position.

Abstract: A radiation imaging apparatus includes: a radiation irradiating apparatus that emits radiation onto a subject; a photography unit that photographs the subject to obtain a photographed image of the subject; and a radiation detector that generates radiation images of the subject, provided with a marker that represents identifying information of the radiation detector on the side thereof that includes a radiation detecting surface. The marker of the radiation detector is detected. The identifying information of the radiation detector is obtained from a marker in the case that the marker is detected.

Abstract: In the radiography system, a camera provided in an X-ray source captures a camera image indicating a usage environment in which an electronic cassette is used. The electronic cassette is inserted into the field of view of the camera. An in-image cassette region of the electronic cassette is detected from the camera image. A cassette ID of the electronic cassette is acquired from the in-image cassette region. The acquired cassette ID is collated with registration information set in a console and a use cassette setting process is performed on the basis of the collation result.

Abstract: A CPU of a console comprises a color image acquisition unit, a distance image acquisition unit, a specification unit, and an estimation unit. The color image acquisition unit acquires a color image, in which a patient and a periphery of the patient are captured, from a visible light camera. The distance image acquisition unit acquires a distance image indicating a distance between a radiation tube and an object, from a TOF camera. The specification unit specifies a kind of the object in the color image. The estimation unit estimates intensity of radiation in an environment captured in the color image based on reference information including the distance image and a specification image as a specification result of the kind of the object.
