Abstract: A tomography apparatus includes a multi-focal point x-ray source, a support to travel a trajectory path, a detector having a plurality of pixels, where one of the multi-focal point x-ray source, the detector, and an item-under-test move on the support. A control processor controls a change in the focal point of the x-ray source at discrete points, or continuously, within a measurement region, the focal point change in a direction retrograde to the support arm travel, a detector memory accumulates a digital value representative of a signal charge from at least a portion of the plurality of pixels, the control processor reconstructs a volumetric image of the item-under-test by processing the detector memory contents. A method for continuous tomosynthesis and a computer-readable medium are also disclosed.

Abstract: An x-ray detector, system and related method are described wherein a light redirection layer is provided and used to redirect light, converted from x-rays by a scintillator, to at least one pixel. The light redirection layer comprises at least one light redirecting cell comprising a channel and a light reflecting region, wherein the channel is arranged relative to the at least one pixel to direct the incoming light away from a non-light sensitive part of the at least one pixel and toward the light sensitive part of the at least one pixel.

Abstract: An x-ray detector comprises: a housing, including a cover removably fastened on a flange of a flanged base and forming a semi-hermetic seal therebetween, the flanged base including a bottom surface and the flange surrounding a perimeter of the bottom surface; and an x-ray imager positioned on the bottom surface, the x-ray imager including a scintillator and an image sensor, wherein the seal semi-hermetically encloses the x-ray imager in the housing, and is positioned nonadjacently to surfaces in contact with the x-ray imager. In this way, a simpler and less costly seal for a digital x-ray panel can be provide; furthermore, the seal is reusable and resealable, facilitating repair and refurbishment of the device.

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.
