Abstract: An X-ray imaging system or radiographic imaging system includes a radiation generating apparatus and a radiographic imaging apparatus. An ionization chamber device is external to the radiographic imaging apparatus, for detecting a dose of the radiation transmitted through an object. Dose sensors are incorporated in the radiographic imaging apparatus, for detecting a dose of the radiation transmitted through the object. An exposure control unit is disposed with the radiation generating apparatus, for shutting off application of the radiation from the radiation generating apparatus according to a detection signal from the ionization chamber device or dose sensors. The ionization chamber device is communicably coupled with the radiation generating apparatus. An operating state of the ionization chamber device and dose sensors is acquired by monitoring, so failure of simultaneous inputting of their detection signals to the exposure control unit is prevented.

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
