摘要： An X-ray CT scanner for imaging an object is provided. The scanner includes an X-ray emitter configured to emit X-ray beams, a detector array including a plurality of detector elements, and a precollimator positioned between the X-ray emitter and the object, the precollimator configured to prevent the emitted X-ray beams from being directly incident on a first subset of the plurality of detector elements, and allow the emitted X-ray beams to be directly incident on a second subset of said plurality of detector elements. A processing device communicatively coupled to the detector array is configured to determine a signature of the object based on a first set of data acquired using the first subset of the plurality of detector elements, and tomographically reconstruct an image of the object based on a second set of data acquired using the second subset of said plurality of detector elements.

摘要： Systems and methods for obtaining and displaying a collimated X-ray image are described. The methods can include providing an X-ray device having an X-ray source, a square or rectangular X-ray detector, and a collimator. The collimator can be sized and shaped to collimate an X-ray beam from the X-ray source that exposes a receptor region on the detector. The collimator can allow the X-ray image received by the X-ray detector to have any suitable shape that allows a relatively large view of the image to be displayed and rotated on the display device without changing the shape or size of the image as it rotated. In some instances, the collimator provides the image with superellipse shapes or cornerless shapes having four substantially straight edges with a 90 degree corner missing between at least two edges that run substantially perpendicular to each other. Other embodiments are described.

摘要： An X-ray radiography system for differential phase contrast imaging of an object under investigation by phase-stepping is provided. The X-ray radiography has an X-ray emitter for generating a beam path of quasi-coherent X-ray radiation, an X-ray image detector with pixels arranged in a matrix, and a diffraction or phase grating, in which the X-ray emitter has an X-ray tube with a cathode and an anode. The X-ray tube is constructed in such a way that an electron ray beam originating from the cathode is associated with focusing electronics which produce, from electrons which are incident on an anode, at least one linear-shaped electron fan beam.

摘要： An X-ray optical device includes a crystal containing a channel, which passes through the crystal and has multiple internal faces. A mount is configured to hold the crystal in a fixed location relative to a source of an X-ray beam and to shift the crystal automatically between two predefined dispositions: a first disposition in which the X-ray beam passes through the channel while diffracting from one or more of the internal faces, and a second disposition in which the X-ray beam passes through the channel without diffraction by the crystal.

摘要： An imaging technique is provided for acquiring scatter free images of an object. The technique includes acquiring a plurality of projection images of the object using a source and a detector oriented at a plurality of projection angles relative to the object, and generating a plurality of scatter free projection images by correcting the plurality of projection images based on respective ones of a plurality of stored scatter images. The scatter images are generated and stored for each of the projection angles by positioning a scatter rejection plate between the object and the detector. The technique further includes reconstructing a three-dimensional image of the object based on the scatter free projection images.

摘要： A method for obtaining a concentrated, monochromatic x-ray beam from a standard x-ray tube or other source of polychromatic emission. X-rays from the anode of the x-ray tube fluoresce an adjoining, independent target that produces a monochromatic spectrum, a portion of which is focused by the x-ray optical system. This two-stage method gives the system considerably versatility without undue loss in signal. The two-stage concentrator makes practical the use of focusing optics in hand-held and portable instruments.

摘要： An X-ray fluorescence analyzer device comprises an X-ray source and a sample window. Between the X-ray source and the sample window there are a collimator plate with a plurality of microscopic pores and an annular plate comprising material essentially opaque to X-rays. The annular plate defines an area transparent to X-rays. The pores in said collimator plate let through collimated X-rays radiated by said X-ray source towards said sample window. The area transparent to X-rays in said annular plate spatially limits in a transverse direction a beam of X-rays radiated by said X-ray source towards said sample window.
