Abstract: The present approach relates to scatter correction of signals acquired using radiation detectors on a pixel-by-pixel basis. In certain implementations, the systems and methods disclosed herein facilitate scatter correction for signals generated using a detector having segmented detector elements, such as may be present in an energy-resolving, photon-counting CT imaging system.

Abstract: A flat panel detector is provided having a circular active area. The flat panel detector is built using complementary metal-oxide-semiconductor (CMOS) tiles. In one implementation, the flat panel detector having a circular active area can be used as a replacement for a conventional image intensifier, including an image intensifier used in a fluoroscopy system.

Abstract: An x-ray detector may comprise: a moisture-impermeable substrate including a non-monolithic conductive portion integrated with a monolithic dielectric portion; a scintillator and an array of CMOS tiles positioned between the scintillator and the substrate; a cover positioned on the substrate and forming a seal therebetween that semi-hermetically encloses the scintillator and the array of CMOS tiles in a covered sealed region; and analog-to-digital electronics conductively coupled to the array of CMOS tiles and to the conductive portion, wherein the conductive portion transmits signals from the covered sealed region to beyond the seal without disrupting a semi-hermeticity of the seal. In this way, sealing of multiply-tiled CMOS image array detectors within a single x-ray detector can be more simply and reliably achieved.

Abstract: The present disclosure relates to the use of X-ray detector cassettes that may be abutted or overlapped to form a detector assembly suitable for imaging objects that are too large to image using a single X-ray detector cassette. Such a detector assembly may be customized in terms of the size and/or shape of the field-of-view (FOV). In certain embodiments the radiation-sensitive electronics (e.g., readout electronics) are positioned to the side of the X-ray detecting components (e.g., scintillator, TFT array, and so forth), allowing the cassette to be thin relative to other detector devices and allowing the electronics to remain outside the X-ray beam path.

Abstract: There is provided an x-ray detector having a number of x-ray detector sub-modules. Each detector sub-module is an edge-on detector sub-module having an array of detector elements extending in at least two directions, wherein one of the directions has a component in the direction of incoming x-rays. The detector sub-modules are stacked one after the other and/or arranged side-by-side. For at least part of the detector sub-modules, the detector sub-modules are arranged for providing a gap between adjacent detector sub-modules, where at least part of the gap is not directed linearly towards the x-ray focal point of an x-ray source.

Abstract: Improvement of the dynamic range of a radiation detector is described. In one embodiment, one or more non-destructive readout operations are performed during a radiation exposure event to acquire data used to improve the dynamic range of the detector. In one implementation, one or more non-destructive readouts of pixels are performed prior to saturation of the pixels during an X-ray exposure so as to obtain non-saturated measurements at the pixels. In an additional implementation, non-destructive readouts of pixels are performed between exposure events so as to obtain an estimate of electronic noise during a multi-exposure examination.

Abstract: The present approach relates to self-calibration of CT detectors based on detected misalignment of the detector and X-ray source. The present approach make the detector more robust to changes against temperature and focal spot movements. The diagnostic image generated by energy resolving calibrated response signals is able to present enhanced features compared to conventional CT based diagnostic images.

Abstract: An imager panel for an x-ray detector for obtaining x-ray images of an object is provided that includes a first portion disposed at the center of the hybrid imager panel that can produce images of a first resolution and a second portion disposed at least partially around the first portion that is capable of producing images of a second resolution. The hybrid imager panel provides a hybrid detector that can be selectively operated to obtain images of varying resolutions corresponding to the first resolution from the first portion, the second resolution from the second portion or a combination thereof.

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.
