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.
