An analytical procedure has been developed for the formulation of tissue substitute materials for use with photons and electrons. This method, called the basic data method, is based upon interaction data and enables two-component substitutes to be formulated with radiation characteristics within specified limits. Another feature of the procedure is the ability, once a primary material has been chosen, to select the best corrective additives from a library of compounds. The theoretical aspects are discussed followed by a discussion of the practical applications of the method.
