An X-ray imaging apparatus displays a bone or soft tissue image of an X-ray image, which corresponds to a region selected by a user, thereby reducing a diagnosis time. In addition, an X-ray imaging system transmits a first energy X-ray image and a second energy X-ray image to a central image management system, and a user control apparatus receives the images from the central image management system and displays a bone or soft tissue image corresponding to the selected region, thereby reducing burden imposed on server capacity of the central image management system as well as reducing a diagnosis time.

A method for performing a job list of radiographic recordings indicated in a radiographic information systems includes communicating the job list to a mobile apparatus, e.g. a smartphone, whereby, in a first step, a peer-to-peer communication is set up between the radiographic information system and the mobile apparatus by a Near Field Communication technique, whereupon the job list is transmitted to the mobile apparatus via a WIFI peer-to-peer communication. A radiographer then completes the job list by using, inter alia, a self-triggering direct radiographic panel and a radiographic generator.

An exposure management system according to an embodiment includes a processing circuitry. The processing circuitry is configured to calculate a deviation index related to a difference between a target exposure index indicating an index of an exposure value that is set as a target of an X-ray image taking process and an image-taking-period exposure index indicating an index of an exposure value observed during the X-ray image taking process. The processing circuitry is configured to control so as to cause a display device to display history information from a predetermined time period indicating at least one selected from between image-taking-period exposure indices and deviation indices.

A radiation detection apparatus includes a sensor base, a sensor substrate supported by the sensor base and configured to output signals from a plurality of pixels for radiation detection, a peripheral member arranged on a periphery of a side surface of the sensor substrate separately from the sensor substrate, supported by the sensor base, and configured not to output the signal for the radiation detection, and a scintillator layer configured to continuously cover the sensor substrate and the peripheral member.
