    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 techniques disclosed may be used to detect and correct channel gain errors resulting from X-ray focal spot mis-alignment during the course of a scan. One benefit of the present invention relative to conventional techniques is that additional hardware is not required for detection of focal spot drift. Instead, the static mis-alignment of each blade is taken into account as part of estimating and correcting X-ray focal spot drift or mis-alignment. In this manner, the risk of image artefacts due to focal spot motion is reduced and the need for costly hardware solutions to detect focal spot motion is avoided.

    Abstract: The present disclosure relates to determining the position of an X-ray focal spot in real time during an imaging process and using the focal spot position to ensure alignment of the focal spot and high-aspect detector elements or to correct for focal spot misalignment, thereby mitigating image artifacts. For example, the focal spot position may be monitored and may be adjusted in real-time using electromagnetic electron beam steering during a scan. Alternatively, previously determined functional relationships between focal spot position and measured data may be applied to address or correct for focal spot misalignment in the acquired data.

    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.

    IPC: A61B6/00

    Abstract: A method for X-ray imaging includes determining one or more pre-shot parameters corresponding to a region of interest in a subject based on an optical image of the region of interest obtained from an optical sensor. The method further includes controlling an X-ray device to generate a pre-shot X-ray image using a first X-ray dosage, based on the one or more-pre-shot parameters. The method also includes determining at least one main-shot parameter based on the pre-shot X-ray image. The method includes controlling the X-ray device to generate a main-shot X-ray image using a second X-ray dosage greater than the first X-ray dosage, based on the at least one main-shot parameter.
