摘要： An imager includes a flat panel configured to collect charges when the imager operates in a full-power charge integration mode. The imager switches to a low-power standby mode immediately after each image acquisition in the full-power charge integration mode. Bias current flowing through the flat panel is monitored in the standby mode. The imager switches to the full-power charge integration mode when detecting a change in the bias current indicating onset of an X-ray exposure.

摘要： An X-Ray matrix imager includes a matrix, a plurality of gate line sets, and a plurality of data lines. The matrix includes a plurality of rows of pixels configured to accumulate charges in response to light or radiation. Each of the gate line sets includes a first gate line coupled to a first pixel among a first row of pixels of the matrix, and a second gate line coupled to a second pixel among the first row of pixels of the matrix, wherein the first pixel is adjacent to the second pixel. Each of the data lines is arranged to be coupled to the plurality of gate line sets for receiving charges accumulated on the first row of pixels. The X-Ray matrix imager is configured to operate based on multiple-gate-line driving scheme and shared-data-line driving scheme.

摘要： 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.
