Flat X-ray detector for measurement of X-ray image dose, comprises scintillator that converts the incident X-ray beam into light, light converting layer and detector element, which receives the light from the scintillator

摘要

The flat X-ray detector for measurement of X-ray image dose, comprises a scintillator (16), which converts incident X-ray beam (14) into light, light converting layer (12), a detector element, which receives the light from the scintillator and emits electrons for production of a image data value, fiber-optic elements (20) that guide a portion of the light from the scintillator to the detector element and to a photosensitive element. The quantity of light led by the optical element is measured. The scintillator is fastened with an adhesive to the light-changing layer. The flat X-ray detector for measurement of X-ray image dose, comprises a scintillator (16), which converts incident X-ray beam (14) into light, light converting layer (12), a detector element, which receives the light from the scintillator and emits electrons for production of a image data value, fiber-optic elements (20) that guide a portion of the light from the scintillator to the detector element and to a photosensitive element. The quantity of light led by the optical element is measured. The scintillator is fastened with an adhesive to the light-changing layer. Each of the optical elements is embedded into the adhesive. The optical element is arranged in a plastic or glass layer that is present between the scintillator and the light-converting layer. The optical element is encased into the plastic or glass layer and is fastened in a recess in the transparent layer. In the X-ray-flat detector, a detector surface is formed, over which the optical elements are evenly distributed. The optical elements are partially formed as strips. Two optical elements guide light to different photocounter (22). An independent claim is included for a method for controlling X-ray tube in flat X-ray detector.
