Abstract

A quantitative measure of the postirradiation reaction in the lung tissue, based on the concept of the equivalent absorber thickness (EAT), has been estimated on the basis of the series of X-ray images of lungs. Radiation effect in normal lung tissue is of major interest in the combined modality treatment of cancer. The proposed method of estimating EAT consists in comparing the digitized image of the tested radiograph with that of a scaling object of known thickness. The resulting scaling function serves to calculate the quantitative measure of the postirradiation reaction in the tissue, which compares favourably with a conventionally used qualitative scale. The method appears to be relatively insensitive to variations in conditions of making and digitizing the X-ray images.
