“…A number of reports pertaining to PXR have been published after the original work of Didenko et al (1985) and Vorobiev et al (1985), but almost all of these have been concerned with production techniques and the theory of PXR. There were no reports on the application of PXR to diffraction among the 32 reports found on PXR found using a CrossSearch program (ISI) using the search items, "parametric" and "X ray".…”

Parametric X rays (PXR) are a new type of X ray that are generated by crystal electron interactions. The Laboratory for Electron Beam Research and Application (LEBRA) at Nihon University generates PXR using a double crystal system generating electrons from a 100 MeV class LINAC. LEBRA PXR has potential for use as a wavelength tunable, ultra high bright X ray source with a macro /micro pulse structure. LEBRA PXR has an energy dispersion in the horizontal axis, assumed to be 0.2% in the experimental window, but can be used as monochromatic X ray source for diffraction using a simple slit system. A diffraction experiment was successfully carried out by applying an 11 keV, or 1.1273 Å, LEBRA PXR. Near perfect crystals, such as graphite used for a monochromator showed sharp diffraction peaks. Clear, transparent mineral quartz and fluorapatite crystals also showed sharp diffraction peaks, while the diffraction peaks from clear calcite and silicon powder were not detected. Possible reasons for the lack of diffraction peaks from these materials are discussed. LEBRA PXR has potential for use in studies on the diffraction of other materials, and is therefore, expected to be a useful tool for crystallographic analysis.

“…They were first observed experimentally by Vorobiev et al (1985) and Didenko et al (1985) in 1985 at Tomsk in the Soviet Union, who identified the radiation from relativistic electrons in a crystal in the Bragg direction. Since then, the term, "parametric X ray radiation", or PXR, has been used in investigations into this phenomenon.…”

Abstract:We demonstrated some different contrasts of cat mandibular squamous cell carcinoma using parametric X-ray radiation at the Laboratory for Electron Beam Research and Application at Nihon University (LEBRA-PXR). A conventional X-ray image revealed a bone tumorous lesion in the mandible. LEBRA-PXR images (20, 25 and 30KeVs) showed some contrasts related to the wavelengths. LEBRA-PXR displayed contrasts which differed from those of conventional X-ray images, suggesting LEBRA-PXR may be useful for diagnostic imaging as a new X-ray source.

“…PXR is the kind of electromagnetic radiation phenomenon that is produced by an interaction between a relativistic charged particle and the periodic structure constituted in a crystalline material . Since the experimental observation of the radiation in 1985, theoretical and experimental studies on the property of PXR have been reported by many authors . However, only a few experiments have been reported on the practical use of PXR…”

Parametric X‐ray radiation as a novel source for X‐ray imaging

et al. 2012

View full text Add to dashboard Cite

A novel X‐ray source based on parametric X‐ray radiation (PXR) has been put into practical use at the Laboratory for Electron Beam Research and Application (LEBRA), Nihon University, Japan. The PXR beam has been generated from a Si single crystal irradiated by a 100‐MeV electron beam from a linac at the LEBRA. In this study, phase‐contrast imaging experiments using a diffraction‐enhanced imaging (DEI) method have been carried out by using the parametric X‐rays at an energy of 17.5 keV. The successful images obtained by the DEI method have shown detailed inner structures of soft biological tissues more clearly as compared with those by conventional absorption radiography. Given the significant properties of the LEBRA PXR source, i.e., compact system, large X‐ray beam irradiation field of approximately 80 mm in diameter and quasi‐monochromaticity, the result suggests a possible construction of a compact linac‐driven PXR‐DEI device and application to medical diagnoses.
