Abstract: An X-ray detector assembly comprising a light attenuator of electro-chromic material, the electro-chromic material having a first electrode layer electrically coupled to a first surface of the electro-chromic material and a second electrode layer electrically coupled to a second surface of the electro-chromic material, wherein the second surface is disposed opposite the first surface, and the light attenuator having a controllable light transmission rate. The X-ray detector further comprising a scintillator deposited on the first electrode layer and a photo detector deposited on the second electrode layer. The photo detector having a sensing surface adjacent to the second electrode layer of the light attenuator. A variable power supply is electrically coupled to the first and second electrode layers of the light attenuator to provide a controllable voltage across the first and second electrode layers to control the light transmission rate of the light attenuator in real time.
