Abstract: A radiographic detector acquires a first partial exposed image signal during an image readout of each of the rows of photosensors, one row at a time. A first scan of each row includes measuring the charge delivered to each cell of the rows, including some rows having partial charge and other rows having full charge, and obtaining a first null image signal during the scan. A second scan includes measuring remaining charge delivered to those rows having partial charge. The null image signal data is subtracted from a sum of the first two scans.

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.

Abstract: Embodiments of DR detector methods and/or apparatus for charge compensation can provide charge injection and/or at least one charge injection circuit that can temporally cancel charge injection to readout circuits resulting from positive (and/or negative) transitions of gate lines for pixel signal readout. In certain exemplary embodiments, DR detector imaging array methods and/or apparatus can provide variable charge injection levels (e.g., voltage or capacitance), variable Tau (e.g., resistance or capacitance), and/or multi-charge injection with staggered timing (e.g., using voltage and/or capacitance steps). In certain exemplary embodiments, DR detector imaging array methods and/or apparatus can provide charge injection compensation on ROIC on mask block basis. In exemplary embodiments, DR detector imaging array methods and/or apparatus can provide voltage reset off-set in readout circuits (e.g., ROICs).
