Radiation Therapy, Secondary Skin Reactions

The purpose of this study is to test a new imaging technology called radioacoustic imaging (RAI) that may help doctors see where radiation is being delivered during proton therapy. During proton therapy, the radiation treatment produces very small sound signals inside the body. This study will use special ultrasound sensors placed on the outside of the body to detect these signals. The information collected may allow researchers to create a picture showing where the radiation dose is being delivered in the body and how much radiation is reaching the treatment area. The goal is to determine whether this technology can safely and accurately measure radiation during proton therapy without requiring any additional procedures or radiation exposure.
