Abstract

This work characterized in terms of the physical properties of heavy elements as reduction filter in the diagnostic radiology. From the results of experimental evaluation, it was founded that in the case of the Ho filter, the variety of X-ray property with kVp was less than those of Ba, Cu and Al. And the ratio of transit-dose to surface and the load of X-ray tube were increased in the order of Al, Ba, Cu and Ho. The contrast of X-ray image showed the higher value in the order of Cu, Al, Ba and Ho.
