Abstract: A radiation shielding system for an x-ray digital detector array includes a first radiation shield having a plurality of shielding pads and a plurality of interstices between the plurality of shielding pads, the plurality of shielding pads having a greater thickness than the thickness of the plurality of interstices. The plurality of shielding pads is configured to be positioned over active components of the x-ray digital detector array and the interstices are configured to be positioned over passive components of the x-ray digital detector array.

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: 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.
