Abstract: A control unit of a console acquires first radiographic image data and second radiographic image data and determines whether a reference line which satisfies a predetermined accuracy for defining a bone mass is capable of being derived, on the basis of a pixel value of an initial soft region of a DXA profile indicating a correspondence relationship between a pixel position and the pixel value in a derivation region including a soft region and a bone region in a DXA image which is a difference image between a first radiographic image and a second radiographic image and is used to derive at least one of bone density or bone mineral content. In a case in which it is determined that the reference line is capable of being derived, the control unit derives the reference line on the basis of the pixel value of the initial soft region.

Abstract: It is detected whether a grid stripe is present in a radiographic image. In a case in which the grid stripe is detected, a process of removing the grid stripe from the radiographic image is performed and the radiographic image is displayed. In a case in which the grid stripe is not detected, a process of removing a scattered component from the radiographic image is performed and a radiographic image subjected to the scattered radiation removal process and a radiographic image before the process are displayed.

Abstract: A radiation image capture device includes plural radiation detection panels that each detect incident radiation that has passed through an imaging subject, that each generate a radiation image, and that are disposed in a row in a direction orthogonal to the radiation incident direction. The radiation image capture device designates a display target image from out of plural radiation images respectively generated by the plural radiation detection panels, and transmits the designated display target image to a console. At least a radiation image other than the display target image is stored in an image memory. The console displays on a display section the received display target image and, in response to data indicating a display request for a radiation image other than the display target image, also displays on the display section the radiation image other than the display target image read from the image memory

Abstract: A communication section having a relatively high communication speed is used for communicating a detection signal or an emission stop signal between a source control device and an electronic cassette. The detection signal is outputted from a detection pixel of the electronic cassette. The emission stop signal depends on a comparison result between an integrated value of the detection signal and an emission stop threshold value. On the other hand, a wireless communication section having a lower communication speed than that of the detection signal and the emission stop signal is used for communicating image data and the like between the electronic cassette and a console.
