COMPUTER DOSE CALCULATION IN RADIATION THERAPY,
Abstract
The purpose of the project was to determine actual doses delivered to an arbitrary set of points in an arbitrary cross-section of a patient undergoing radiation therapy. This requires modification of an existing program which computes and represents diagrammatically percentage depth doses. The effect of inhomogeneities upon delivered dose must be accounted for in both rotational and fixed field treatment therapy. It was found that suitable modifications and additions to the existing program resulted in accurate determinations of delivered dose at arbitrarily-selected points of interest. He found it possible to translate measured exposure in air to absorbed dose in tissue, taking into account the location and size of inhomogeneities effecting delivered doses. In addition, it was found that computerized techniques offered improvement over manual techniques in accuracy, cost, expenditure of time, and generality. (Author)
