Development of X-ray Spectroscopic System Using Medical X-ray Tube
We developed a practical spectroscopic system using the white X-rays that arise from a medical X-ray tube. As monochromatic X-rays are more desirable than white X-rays to examine the energy characteristic of the system's image detector, we generated monochromatic X-rays, using a Si crystal, it examine the characteristic. The FWHM (full width at half maximum) and the output X-ray intensity were measured. The following results were obtained. (1) The developed system can be used in the energy region of diagnostic radiography. (2) The FWHM is from 0.15 to 1.4 keV. (3) The intensity of monochromatized X-rays at 50 keV is about 1 % of the total intensity of white X-rays.
