Dosimetric evaluation of skin collimation with tungsten rubber for electron radiotherapy: A Monte Carlo study

摘要

Skin collimation provides a sharp penumbra for electron beams, while the effect of bremsstrahlung from shielding materials is a concern. This phantom study was conducted to evaluate the safety and efficacy of a real‐time variable shape rubber containing‐tungsten (STR) that can be placed on a patient’s skin.
