    摘要： A radiography system includes a radiation source that emits radiation, an electronic cassette that receives the radiation and detects a radiographic image, a portable first retainer that holds the electronic cassette, a string that is attached to the first retainer, and a camera that images the string. The first retainer includes a lock portion and a movable portion as an inclination change mechanism that can change an inclination of the electronic cassette with respect to the radiation source. The string and the camera constitute a first detection mechanism that detects an inclination of the electronic cassette about an X-axis which intersects a Z-axis and is directed toward the radiation source in a case in which a radiation detection surface of the electronic cassette and the radiation source are disposed to face each other.

    摘要： 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.

    摘要： A portable X-ray imaging apparatus includes an electronic cassette for imaging of an X-ray image and transmitting the X-ray image wirelessly. An image receiving unit communicates with the electronic cassette and receives the X-ray image wirelessly. A passive monitoring device receives ambient electromagnetic waves to measure communication environment by passive monitoring. An active monitoring device performs data communication between the electronic cassette and the image receiving unit to measure the communication environment by active monitoring. Furthermore, an evaluation device detects a cause of a communication failure by considering a result of the passive monitoring and a result of the active monitoring. The evaluation device detects that the cause of the communication failure is a blocking object blocking radio waves or a relative position between the electronic cassette and the image receiving unit according to the results of the passive and active monitoring.

    摘要： An electronic cassette includes a first radiation detector for still imaging and a second radiation detector for fluoroscopic imaging. The first radiation detector includes a first photo detection device and a luminous device. The luminous device generates visible light by absorbing radiation transmitted through the first photo detection device. The first radiation detector detects the visible light generated by the luminous device. The second radiation detector is constituted by the luminous device and a second photo detection device disposed downstream of the luminous device in an optical path direction of the radiation. The second photo detection device detects the visible light generated by the luminous device. The second radiation detector is changed over to the first radiation detector, so that still imaging can be started by rapid setting during operation of fluoroscopic imaging.
