Abstract: An x-ray transmission spectrometer system to be used with a compact x-ray source to measure x-ray absorption with both high spatial and high spectral resolution. The spectrometer system comprises a compact high brightness x-ray source, an optical system with a low pass spectral filter property to focus the x-rays through an object to be examined, and a spectrometer comprising a crystal analyzer (and, in some embodiments, a mosaic crystal) to disperse the transmitted beam, and in some instances an array detector. The high brightness/high flux x-ray source may have a take-off angle between 0 and 15 degrees, and be coupled to an optical system that collects and focuses the high flux x-rays to micron-scale spots, leading to high flux density. The x-ray optical system may also act as a “low-pass” filter, allowing a predetermined bandwidth of x-rays to be observed at one time while excluding the higher harmonics.

Abstract: Linear ribs are formed radially with a center at a through-hole on one face of an X-ray transmissive film (radiolucent film) in an X-ray transmissive window (radiolucent window) to be used for an X-ray detector (radiation detector). The X-ray transmissive window faces a sample. A beam for irradiation to the sample passes through the through-hole, and X-rays (radiation) are radially emitted on a line extending through the through-hole and enter the X-ray transmissive window. Since the linear ribs are formed radially with the center at the through-hole, even X-rays entering at shallow angles with respect to the X-ray transmissive window are transmitted through the X-ray transmissive window at a probability equivalent to X-rays entering at deep angles. More X-rays are transmitted through the X-ray transmissive window, and thus the X-ray detector can detect X-rays with high efficiency.

The control unit controls capturing of the taken frame images according to a result of the determination of the change determination unit.

Abstract: An X-ray apparatus for image acquisition and a related method. The apparatus comprises a field-of-view corrector (CS) configured to receive a scout image (SI) acquired by the imager with a tentative collimator setting in a pre-shot imaging phase where said imager operates with a low dosage radiation cone causing the detector to register the scout image. The low dosage cone has, in the detector's image plane, a first cross section smaller than the total area of the detector surface. The field-of-view corrector (CS) uses said scout image to establish field-of-view correction information for a subsequent imaging phase where the imager is to operate with a high dosage radiation cone, the high dosage higher than the low dosage.

Abstract: A phase grating for a phase contrast X-ray imaging device has a transverse surface which is to be aligned substantially transversely with respect to a radiation incidence direction and which is spanned by an x-axis and a y-axis perpendicular thereto. The phase grating is formed from a multiplicity of grating webs composed of a basic material, which are arranged alternately with optically denser interspaces. The grating webs subdivide the transverse surface into grating strips which are in each case elongated in the y-direction and which are lined up parallel alongside one another in the x-direction. The phase grating has in each grating strip along a z-axis, which is perpendicular to the transverse plane, a homogeneous total thickness of the basic material which always differs between adjacent grating strips. At least one grating web extends within the transverse surface over a plurality of grating strips.
