  • Patent number: 10887534
    Abstract: A digital radiographic detector detects a first mode signal and dispositions a received digital image according to a procedure associated with the first mode signal. A second mode signal results in dispositioning a second received digital image according to a second image disposition procedure. The detector determines the first mode or second mode based on the signal's pulse width, a number and timing of rising edges (peaks), a digital code, a voltage level, or a combination thereof.

  • Patent number: 10732301
    Abstract: A digital radiographic detector outputs positive read out signals that may oscillate. The presence of negative going portions of the read out signals may be used to determine that the detected positive signals are a result of noise, while an absence of the negative going portions may be used to determine that x-rays are impacting the detector.

  • Patent number: 10230906
    Abstract: A method of operating a DR detector including sequentially capturing image frames in the detector that include at least one dark image. The dark image is stored and a statistical measure for a subset of pixels in a captured image frame is compared with the same statistical measure of a subset of pixels in the stored dark image to detect an x-ray beam impacting the detector. An x-ray beam-on condition is indicated if a sufficient difference in intensity between the pixel subsets is detected. At least one more image frame is captured in the detector after detecting the x-ray beam. The current captured image and the at least one more image frame are added and the dark image is subtracted to form the exposed radiographic image.
