摘要： A method and circuit for reducing correlated noise in imagers is disclosed. According to an aspect, correlated noise is reduced by coupling the reference inputs of imager amplifiers to common voltage sources. The reference inputs of differential amplifiers on the imager can be coupled to common noise sources such as the imager low gate voltage and array bias voltage through suitably chosen capacitances.

摘要： A method for providing X-ray image data signals corresponding to a selected portion of a two-dimensional image at an enhanced image resolution. During selective exposure of an X-ray receptor to X-ray radiation corresponding to the subject image, image pixel data corresponding to the region of interest (used pixels) are read out with normal pixel data pixel discharge times and at the normal pixel data rate, while image pixel data corresponding to the region not of interest (unused pixels) are read out also with normal pixel data pixel discharge times and at either the normal pixel data rate or an increased pixel data rate. During such pixel data readout intervals, the X-ray radiation exposure can be continuous or selectively pulsed.

摘要： A multiple mode digital X-ray imaging system providing for preprocessing “binning” of analog pixel signals from a detector array by selectively summing, within the detector array, adjacent pixel charges on a row-by-row basis and selectively summing, within detector array readout circuits, the previously summed pixel charges (by rows) on a column-by-column basis. An array, or mapping, of “defective pixel” flags is used to identify defective pixels within the detector array, with such flags being added to, or inserted into, the incoming data stream for dynamic processing along with the incoming pixel data. A buffer and filter is used to perform still image capture during the radiographic mode of operation and to recursively filter incoming data frames during the fluoroscopic mode of operation by summing a scaled amount of pixel data from prior data frames with a scaled amount of incoming pixel data from the present data frame.

摘要： A current mode analog signal multiplexor includes multiple input multiplexed differential amplifiers, and an output differential current amplifier. An input multiplex control signal selects and enables one of the input multiplexed differential amplifiers for buffering and steering the input signal current to one side of the output differential current amplifier. The reference amplifier drives the other side of the output differential current amplifier. The output node of the output differential current amplifier remains at a substantially constant voltage potential while providing an output current which varies in relation to the selected input signal.
