  • Patent number: 10686003
    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.

  • Patent number: 10036814
    Abstract: An x-ray image detector includes a light image sensor having a depth, a front side comprising a sensing surface, and a back side. The x-ray image detector further includes a substrate plate on the back side and surrounding the depth of the light image sensor such that the substrate plate forms a lip around the light image sensor. The lip is level with the front side of the light image sensor. The x-ray image detector further includes a scintillator over the sensing surface of the light image sensor and at least a portion of the lip.

  • Patent number: 10032813
    Abstract: Fabrication and use of an X-ray detector scan interface having separate enable and reset lines for each line (e.g., row) of pixels is described. In certain implementations, the respective enable and reset lines are connected such that activation of an enable line for a given line of pixels is concurrent with activation of a reset line for a different (e.g., preceding) row of pixels. In this manner, readout of one row of pixels is performed in conjunction with resetting the row of pixels readout in the preceding operation. In another technical implementation, a non-rectangular detector is divided into quadrants, with alternating quadrants configured for scan module or data module operations such that no quadrant has overlapping scan and data interconnections at the connection finger regions.
