Imaging by using proton-induced quasi- monochromatic X-ray emission
Quasi-monochromatic X-ray emission induced by MeV-proton bombardment onto metallic targets was applied to radiography of small samples. The X-ray energy was adjusted in the range of z4–23 keV by changing the target material. The radiograms were recorded on an imaging plate. A small phantom made of Lucite was prepared for the test of photography using a contrast medium (RuCl3$H2O; ruthenium chlo...
متن کاملProton-induced X-ray Emission
Black particles, collected by filtration (1.2~pm pore size) from the anoxic waters of a soft-water lake, were examined by a scanning proton microprobe which permitted quantitative elemental analysis by proton-induced X-ray emission (PIXE) and Rutherford backscattering (RBS). There was a uniform distribution of sulfur across the filter, but Fe, and to a lesser extent, Mn, was localized in -5-pm-...
متن کاملA proton induced X-ray emission (PIXE) analysis of concentration of trace elements in varicose veins
Background: Proton induced X-ray emission (PIXE) has been applied as reliable and improved techniques in this study to compare concentration of various trace elements in normal and abnormal varicose veins. Materials and Methods: Five samples from normal veins and 13 samples from varicose veins bombarded by 2.0 MeV energy proton beams produced by a Van de Graff accelerator in vacuum. T...
متن کاملEngineering iodine-doped carbon dots as dual-modal probes for fluorescence and X-ray CT imaging
X-ray computed tomography (CT) is the most commonly used imaging technique for noninvasive diagnosis of disease. In order to improve tissue specificity and prevent adverse effects, we report the design and synthesis of iodine-doped carbon dots (I-doped CDs) as efficient CT contrast agents and fluorescence probe by a facile bottom-up hydrothermal carbonization process. The as-prepared I-doped CD...
متن کاملGraphene Quantum Dots-Coated Bismuth Nanoparticles for X-ray CT Imaging-Guided Photothermal therapy of Cancer Cells
Introduction: Theranostic nanoparticles, which integrate both diagnostic and therapeutic capabilities into one nanoagent, has great promise to ablate more effective tumoral tissue by optimizing and real-time monitoring treatment interventions, as well as monitoring therapeutic response to corresponding effect. Multifunctional theranostic nanoagent based on graphene quantum dots...
