A linac-based X-ray system for cargo scanning and imaging applications uses linac design, RF power control, beam current control, and beam current pulse duration control to provide stable sequences of pulses having different energy levels or different dose.

An aligning bite of an X-ray device for aligning a subject to an X-ray imaging point and an X-ray device having the same are disclosed. The aligning bite of an X-ray may include a support unit being rotatably connected to a bite stand supporting the aligning bite, and a bite unit being rotatably connected to the support unit, wherein the support unit may include a link frame supporting the bite unit by connecting the bite unit to the bite stand, a first joint rotatably connecting one side of the link frame to the bite stand, a second joint rotatably connecting the bite unit to another side of the link frame, and a third joint being provided between the first joint and the second joint so as to allow the link frame to be folded.

A sample holder for X-ray analysis is provided with: a first annular member; a second annular member configured to be inserted and fitted into the first annular member in a state where a first film is sandwiched between the first annular member and the second annular member while the first film is being stretched to cover a lower opening portion of the second annular member; and a third annular member configured to be inserted and fitted into the second annular member in a state where a second film is sandwiched between the second annular member and the third annular member while the second film is being stretched to cover a lower opening portion of the third annular member. The first film and the second film are configured to hold a sample for X-ray analysis by sandwiching the sample between the first film and the second film.

An X-ray source with optical indication of radiation, which can be used in various measuring devices for parameters control and visualization of structure of industrial and biological objects, is proposed. The source comprises a vacuum housing, an anode irradiated by electrons and generating the divergent flux of radiation, an exit window for X-ray radiation, means for optical indication of X-ray radiation beam including a source of optical radiation and an optical mirror. The anode is made composite in the form of a thin film and a radiolucent substrate luminescent in the optical range. The anode structure is an exit window of the source, and behind it the coaxially arranged means of collimation and focusing of X-ray and optical radiation and means of optical visualization of X-ray focus are mounted. The proposed device significantly increases the accuracy and informativity of optical indication of X-ray radiation parameters.

A method and mechanical design for a thin-film diamond crystal mounting apparatus for coherence preservation x-ray optics with optimized thermal contact and minimized crystal strain are provided. The novel thin-film diamond crystal mounting apparatus mounts a thin-film diamond crystal supported by a thick chemical vapor deposition (CVD) diamond film spacer with a thickness slightly thicker than the thin-film diamond crystal, and two groups of thin film thermal conductors, such as thin CVD diamond film thermal conductor groups separated by the thick CVD diamond spacer. The two groups of thin CVD film thermal conductors provide thermal conducting interface media with the thin-film diamond crystal. A piezoelectric actuator is integrated into a flexural clamping mechanism generating clamping force from zero to an optimal level.

A computed tomography (CT) imaging apparatus includes an X-ray source to emit X-rays; a plurality of photon-counting detectors (PCDs) arranged in a circular ring between the X-ray source and a CT detector; and processing circuitry to cause the X-ray source and the CT detector to perform a helical scan of an object to obtain projection data; extract, from the obtained projection data, a plurality of sets of projection data corresponding to a plurality of X-ray tube positions of the helical scan; and combine the plurality of sets of extracted projection data to obtain a scanogram.
