| 内容記述 | A fundamental examination of X-ray spectra analysis for the improvement of clinical technique and x-ray equipment was conducted. A comparison of X-ray spectrum of the water and acrylic resin showed that the X-ray transmission ratio of acrylic resin was high for low energy regions, and low for high energy regions. This constitutes a considerable problem when acrylic resin is used. When filters made of aluminum, copper, niobium and molybdenum were inserted, it was found that the attenuation ratios could be obtained with these filters as if the attenuation ratio was calculated by using mass attenuation coefficients of Hubbell without stripping correction. The addition of the Nb and Mo filters reduced in the photons of lower x-ray energy, and transmitted the photons of high-energy x-rays. The addition of Al filter tended to have the effect, but less evident, while the effect of the Cu filter was between that of Nb and Mo and of Al. The X-ray transmission ratio of the screen was also measured. For the range from 40 keV to 70keV, the orthochromatic screen should reduced the photons of x-ray, but for any other range the regular screen should reduced the photons. | |||||
