Abstract

The aim of in-vivo skin dosimetry is to measure the absorbed dose to the skin during radiotherapy, when treatment planning calculations cannot be relied on. It is of particularly importance in hypo-fractionated stereotactic modalities, where excessive dose can lead to severe skin toxicity. Currently commercial diodes for such applications are not available for medical physicists. In this study, we investigate a new detector for skin dosimetry based on a silicon epitaxial diode, referred to as the skin diode.
