| Popis: |
A method is described for determining the efficient atomic number of inclusion-tissue substance, visualized in image, by the characteristic angle estimated by means of spectronazal X-ray detector. Described are study results of the influence of inclusion's geometric dimensions and of the whole radiation filtration exerted on the value of characteristic angles for different substances. The experimental values of effective atomic numbers are shown to fit well, within the range limited by radiation contrast, the theoretical ones. |
