Synchrotron radiation X-ray microfluorescence techniques and biological applications
نویسنده
چکیده
Synchrotron X-ray imaging systems with fluorescence techniques was developed for biomedical researches in Brazilian Synchrotron Laboratory. An X-ray fluorescence microtomography system was implemented to analyse human prostate and breast samples and an X-ray microfluorescence system was implemented to study bone sites of human and animal samples with and without bone disorders.

متن کاملWavelength-dispersive spectrometer for X-ray microfluorescence analysis at the X-ray microscopy beamline ID21 (ESRF)
The development of a wavelength-dispersive spectrometer for microfluorescence analysis at the X-ray Microscopy ID21 beamline of the European Synchrotron Radiation Facility (ESRF) is reported. The spectrometer is based on a polycapillary optic for X-ray fluorescence collection and is operated in a flat-crystal geometry. The design considerations as well as operation characteristics of the spectr...
متن کاملNon-destructive characterization of CoTSPc electrochemically deposited on gold electrodes by means of synchrotron X-ray microfluorescence
This paper gives a detailed study of the morphology and heterogeneity of an electrodeposited cobalt tetrasulphophthalocyanine tetrasodium salt (Co(II)TSPc) layer. A continuous potential cycling of the electrode between two potentials can lead to a modification of a bare electrode. During the modification, a non-destructive characterization by means of scanning synchrotron X-ray fluorescence rad...
متن کاملAn in-vivo study on the energy dependence of X-ray biological effectiveness
Background: The International Commission on Radiological Protection (ICRP) has attributed the same relative risk for X and gamma radiations of all energies. Several studies have proven that the biological effect of low energy photon is more than that of higher ones. The assessment of risks is important due to the wide use of low energy X-rays for mammography screening and other diagnostic appli...
متن کاملAn Overview of Technological Developments in Medical Applications of X-Rays and Radioactivity
The years 1895 to 1898 were momentous for their impact on health and human well beings. First, Wilhelm Roentgen noted a glowing fluorescent screen, caused by invisible rays. This event subsequently led to the discovery of X-rays in 1895, and thus the birth of the “atomic ageâ€. Next Becquerel’s investigations of these mysterious rays led to his experiments with uranium salt crystals. He th...
