    Abstract: Various approaches are discussed for using four-side buttable CMOS tiles to fabricate detector panels, including large-area detector panels. Fabrication may utilize pads and interconnect structures formed on the top or bottom of the CMOS tiles. Electrical connection and readout may utilize readout and digitization circuitry provided on the CMOS tiles themselves such that readout of groups or sub-arrays of pixels occurs at the tile level, while tiles are then readout at the detector level such that readout operations are tiered or multi-level.

    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 disclosure relates to fabrication and use of a phase-contrast imaging detector that includes sub-pixel resolution electrodes or photodiodes spaced to correspond to a phase-contrast interference pattern. A system using such a detector may employ fewer gratings than are typically used in a phase-contrast imaging system, with certain functionality typically provided by a detector-side analyzer grating being performed by sub-pixel resolution structures (e.g., electrodes or photodiodes) of the detector. Measurements acquired using the detector may be used to determine offset, amplitude, and phase of a phase-contrast interference pattern without multiple acquisitions at different phase steps.
