Brief
Multibeam X-ray microscopy is a novel 3D imaging technique that uses polycapillary optics and a photon-counting hybrid pixel detector to generate and detect multiple X-ray beams for high-resolution imaging with reduced exposure times.
Summary
The article, "Multibeam 3D X-ray microscopy with polycapillary optics and EIGER2 R detector" by K. M. Sowa and P. Korecki, details a novel 3D imaging setup for high-resolution imaging. The setup uses polycapillary optics and a photon-counting hybrid pixel detector to generate and detect up to 1000 X-ray beams. This multi-beam setup has several advantages over traditional methods, including an improved signal-to-noise ratio, the ability to obtain depth-resolved images from a single exposure, and the capability to perform high-resolution micro-tomographic scans without sample translations or limitations on the angular range.
The setup consists of an X-ray tube, polycapillary optics with a multi-pinhole mask, and a photon-counting hybrid pixel detector. X-rays are generated by the tube, shaped by the polycapillary optics, and then detected by the detector after passing through the sample.
The article highlights three key applications of this technology: signal-to-noise reduction, plenoptic X-ray microscopy, and X-ray microtomography. Image multiplexing, enabled by the multiple beams and the characteristics of the HPC pixel detector, significantly improves the signal-to-noise ratio. This technique allows for shorter acquisition times without compromising image quality. The multi-beam setup also enables plenoptic X-ray imaging, which allows for depth-resolved imaging from a single exposure, similar to tomosynthesis. Lastly, the article describes how this technology is used for high-resolution X-ray microtomography. The narrow cones of the X-ray beams allow for high-resolution imaging, and the use of multiple beams allows for faster acquisition times.
The article concludes by noting the potential of multi-beam X-ray microscopy for high-resolution 3D X-ray imaging, particularly with the future use of more powerful X-ray tubes and large-area hybrid pixel detectors.
