Assignee: GE PRECISION HEALTHCARE LLC
Field: Environmental technology (Chemistry)
Classification: CPC G  A | IPC A  G

Claim 0:
1. A phase-contrast imaging detector, comprising:
a plurality of pixels, each pixel comprising:
a detection material that generates a measurable parameter in response to X-ray photons; and
a plurality of sub-pixel resolution readout structures, wherein 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;

readout circuitry configured to read out signals from the plurality of sub-pixel readout structures;
wherein the plurality of sub-pixel resolution readout structures comprises two or more electrodes having alternating arms that form an interleaved comb structure.
