Clear Vision REF series X-ray flat panel detectors incorporate the proven technology of amorphous silicon. The amorphous silicon photodiode array and TFT underneath convert invisible X-ray photons into visible photons, and then into electric charges. The electron signals are measured and amplified in the data line, and then converted to digital signals by the Analog/Digital converter, Finally, the digital signals are transmitted to a PC for processing to from an image. High DQE, high spatial resolution, extraordi- nary dynamic range and ultra-low noise are hallmarks of our Clear Vision REF series Each Clear Vision REF detector is submitted for FDA and CE approval
