  • Patent number: 10054695
    Abstract: The invention relates to a two steps image capture panel for recording x-ray image information. More particularly, the invention relates to a method and an apparatus for directing the internal electric field to capture the x-ray image first on an insulating surface, avoiding charge injection noise from the insulating surface, and then re-directing the internal electrical field to transfer the image charge from the insulating surface to a conductive readout electrode with electric field sufficient for charge gain during image readout.

  • Patent number: 5895936
    Abstract: An image capture panel particularly useful in radiographic application is disclosed, in which the active image capture area of individual sensors having top and bottom charge collecting microplates arrayed in rows and columns is extended by providing an additional charge capture conductive strip over sensor areas which are not normally covered by a charge collecting microplate. The strip may be made integral with the top microplate or may be separate and electrically connected thereto at a single point.

  • Patent number: 5661309
    Abstract: An electronic cassette contains an X-ray image capturing panel comprising a solid state transistor array and storage capacitors on which is built a layered structure including a photoconductive layer. The storage capacitors capture electrical charges generated in the photoconductive layer by incident X-radiation and the image-wise charges are read out by the transistor array. The cassette contains an internal power supply and a built-in image storage medium among a plurality of electronic components to allow self-contained operation and temporary recording of digitized values which are representative of the pattern of incident X-radiation.

  • Patent number: 5648660
    Abstract: A process and related apparatus for reducing noise due to addressing and switching the detection elements in a radiation detecting panel comprising an array of detection elements. Noise reduction is achieved in two steps, first by the use of a sample and hold circuit which compares a first signal indicative of switching noise held in a sample and hold circuit with a second signal which includes the switching noise and the desired data signal. The second step includes further reducing noise in the output signal present during readout of the detection elements by comparing the signal from certain elements in the array which have not been exposed to radiation with the signal from the exposed elements in the array to obtain an output with significantly reduced noise.
