title: Radiotherapy treatment planning for patients fitted with prostheses.
abstract: The effects of prostheses on radiotherapy treatment planning are discussed. The compositions of commonly used materials are tabulated. Sample plots show the size of perturbations produced by typical absorbers at 8 MV. A technique for estimating the density of a prosthesis in a patient is demonstrated and the effects of prostheses on representative radiotherapy plans are illustrated.
