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.

Abstract: The present approach relates to the use of detector elements (i.e., reference detector pixels) positioned under septa of an anti-scatter collimator. Signals detected by the reference detector pixels may be used to correct for charging-sharing events with adjacent pixels and/or to characterize or correct for focal spot misalignment either in real time or as a calibration step.

Abstract: A method for imaging an object to be reconstructed includes acquiring projection data corresponding to the object. Furthermore, the method includes generating a measured sinogram based on the acquired projection data and formulating a forward model, where the forward model is representative of a characteristic of the imaging system. In addition, the method includes generating an estimated sinogram based on an estimated image of the object and the forward model and formulating a statistical model based on at least one of pile-up characteristics and dead time characteristics of a detector of the imaging system. Moreover, the method includes determining an update corresponding to the estimated image based on the statistical model, the measured sinogram, and the estimated sinogram and updating the estimated image based on the determined update to generate an updated image of the object. Additionally, the method includes outputting a final image of the object.
