Abstract: The present approach relates to the use of augmented or enhanced reality to facilitate positioning of one or more of a patient, X-ray source, or detector during an image acquisition. In certain implementations, sensors and/or cameras provide quantitative information about the position of system components and the patient, which may be used to generate a positioning image based upon reference to an anatomic atlas.

Abstract: The present approach relates to self-calibration of CT detectors based on detected misalignment of the detector and X-ray source. The present approach make the detector more robust to changes against temperature and focal spot movements. The diagnostic image generated by energy resolving calibrated response signals is able to present enhanced features compared to conventional CT based diagnostic images.

Abstract: A digital X-ray detector is provided. The digital X-ray detector includes multiple pixels, each pixel including a pinned photodiode, and multiple readout channels coupled to each pinned photodiode, wherein each readout channel includes at least one charge-storage capacitor, an amplifier, and a transfer gate. The digital X-ray detector also includes control circuitry coupled to each pixel of the multiple pixels and configured to selectively control a flow of photocharge generated by each pinned photodiode to a respective at least one charge-storage capacitor of each respective readout channel via control of each respective transfer gate of each respective readout channel.

Abstract: An imager tile including four-side buttable sub-imager pixel arrays with on-chip digitizing electronic readout circuit. Pixel groupings formed from among the plurality of imagers. Readout electronics including a buffer amplifier for each of the pixel groupings are connected to respective outputs of buttable imagers. Shared analog front ends connect to respective buffer amplifiers of pixel groupings. An analog-to-digital converter at a common centroid location relative to the shared analog front ends includes three data lines—selection input/output line to individually select an output, a clock input line, and a shared digital output line. A pixel output from a respective buffer amplifier is addressable by data provided on the selection input/output line, and the pixel output is provided on the shared digital output line. The I/O lines connected to a programmable logic device where the imager serial data input is output as a massively parallel data stream.
