Abstract
An electronic cassette contains an X-ray image capturing panel comprising a solid state transistor array and storage capacitors on which is built a layered structure including a photoconductive layer. The storage capacitors capture electrical charges generated in the photoconductive layer by incident X-radiation and the image-wise charges are read out by the transistor array. The cassette contains an internal power supply and a built-in image storage medium among a plurality of electronic components to allow self-contained operation and temporary recording of digitized values which are representative of the pattern of incident X-radiation.
