Evaluation of Radiobiological Effects in Skin Toxicities for Breast Cancer Patients With Pencil Beam Scanning Proton Therapy

"Part of the normal proton therapy process is to have a CT scan (called a CT simulation) performed that is used to create a proton treatment plan. A proton treatment plan is a computer model of the proton beam that is used to calculate where the protons will go inside the body. During the treatment planning process, the clinical team works to find the best possible placement of the protons. This study uses a process called Spot Delete to keep protons from stopping in the skin, which is believed to be related to skin reddening. Spot Delete is a software application that was developed at the Thompson Proton Center and is used in the treatment planning process."
