A 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 کاملInvestigation of heavy trace elements in neoplastic and non-neoplastic human thyroid tissue: A study by proton-induced X-ray emissions.
Background: Within the context of developing techniques to facilitate the diagnosis of the thyroid diseases, the elemental composition of pathological thyroid tissue (neoplastic and non-neoplastic) was investigated by proton induced X-ray emission. The PIXE has been widely used as a sensitive technique for trace elemental analysis in both biological and medical fields. Materials and Methods: Th...
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 کاملImaging 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...
