Abstract

A thin photo detector (5) forming a single sensitive surface is positioned in front of a scintillating or fluorescent material (3) in front of an image detector (1). The light created in the scintillating or fluorescent material when the present device is subject to X-ray radiation then will hit both the photo detector and the image detector. An electric signal created in the photo detector (5) may then be utilised for deciding status of the imaging system and define a status of the imaging system dependent on whether exposure (radiation source active) takes place or not. The photo detector may in a preferred embodiment for instance constitute amorphous silicon deposited onto a substratre transparent for X-ray radiation and positioned close to a scintillating or fluorescent material in front of an image detector. However the photo detector in still another embodiment may as well be made from a semiconductor polymer. The three main components, photo detector (5), fluorescent screen (3) and image detector (1) are easily integrated into one imaging component. Due to the compact design possible, the present invention may advantageously be used for instance for dental X-ray examinations.
