Influence of hip prostheses on high energy photon dose distributions

Int J Radiat Oncol Biol Phys. 1990 Feb;18(2):455-61. doi: 10.1016/0360-3016(90)90115-z.

Abstract

Radiotherapy treatment of patients having a hip prosthesis is a common problem facing dosimetrists and physicists when the treatment plan requires irradiation of the pelvic area. To quantify the perturbation of these devices, attenuation studies were done with 6 and 18 MV photon beams using various hip prostheses models with varying size and composition. These studies have shown that an attenuation of as much as 50% can be found in a single beam profile under the prosthesis. We have studied the capability of a dose planning system to predict the transmission of these devices as compared with measurements.
