Abstract: A radiation detector includes a support table, a sensor panel, a fixing member, and a contact member. An attachment surface having an arc surface shape is formed in the support table. The sensor panel has an imaging region in which a plurality of pixels detecting radiation are two-dimensionally arranged. A first surface of the sensor panel is attached to the attachment surface following the arc surface shape. The fixing member partially fixes the first surface to the attachment surface. The contact member comes into contact with a second surface of the sensor panel which is opposite to the first surface to suppress the lifting of the sensor panel from the support table.

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.

Abstract: A control device includes a control unit and a determination unit. The control unit controls an operation of radiation tubes such that radiation is emitted at irradiation positions whose number is smaller than the total number of irradiatable positions preset so as to correspond to irradiation angles. The determination unit determines whether or not the radiation needs to be additionally emitted at the irradiatable positions different from the irradiation positions in order to obtain the tomographic image with an image quality level required for diagnosis, on the basis of a determination image obtained by the emission of the radiation at the irradiation positions.

Abstract: A console includes an image processing unit, a defective pixel map data acquisition unit, a failure condition estimation unit, a notification unit, and a display unit. The defective pixel map data acquisition unit acquires defective pixel map data output from a radiography unit. The failure condition estimation unit receives the defective pixel map data acquired by the defective pixel map data acquisition unit and estimates the failure probability of the radiography unit or the usage state of the radiography unit at the time of failure.
