More Information
Summary:An X-ray imager includes a photo detector, a pixel array, a scan line and a data line. The photo detector includes a plurality of X-ray sensitive particles that are configured to be electrically isolating and to generate charge carriers upon absorption of X-ray photons. In one example embodiment, the photo detector includes a layer of an electrically isolating material, within which the plurality of X-ray sensitive particles are distributed. The pixel array includes multiple pixels each defined by a space between a first surface and a second surface of the layer. The scan line is configured to activate a corresponding row of the pixels in the pixel array. The data line is configured to read data from a corresponding column of the pixels in the pixel array.
