Publication number: 20240085575Abstract: A phase-contrast imaging detector includes a plurality of pixels. Each pixel includes a detection material that generates a measurable parameter in response to X-ray photons. Each pixel also includes a plurality of sub-pixel resolution readout structures. The sub-pixel resolution readout structures are in an alternating pattern with a spacing therebetween that is larger than a frequency of a phase-contrast interference pattern but small enough to enable charge sharing between adjacent sub-pixel resolution readout structures when an X-ray photon hits between the adjacent sub-pixel resolution readout structures. The phase-contrast imaging detector also includes readout circuitry configured to read out signals from the plurality of sub-pixel readout structures. The plurality of sub-pixel resolution readout structures includes two or more electrodes having alternating arms that form an interleaved comb structure.Type: ApplicationFiled: November 21, 2023Publication date: March 14, 2024Inventors: Uwe Wiedmann, Biju Jacob, Brian David Yanoff

Patent number: 11389124Abstract: 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.Type: GrantFiled: February 12, 2020Date of Patent: July 19, 2022Assignee: General Electric CompanyInventors: Uwe Wiedmann, Biju Jacob, Peter Michael Edic, Brian David Yanoff

Patent number: 10686003Abstract: 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.Type: GrantFiled: December 31, 2015Date of Patent: June 16, 2020Assignee: GENERAL ELECTRIC COMPANYInventors: Biju Jacob, Habib Vafi, Brian David Yanoff, Jeffery Jon Shaw, Jianjun Guo
