WebJul 27, 2024 · SBRT allows for simultaneous integrated boosts (SIB) to the tumor vessel interface (TVI). In contrast, HIGRT delivers a homogeneous dose without a boost to the TVI in order to minimize normal tissue dose. Each site must be credentialed for SBRT prior to enrollment and all radiation plans must be centrally reviewed prior to treatment.

WebOct 18, 2024 · SBRT has a narrower beam of radiation that allows us to more precisely target the tumor. Also, when a patient breathes, the tumor moves about a centimeter. To protect normal tissues from radiation exposure, we can track the tumor’s movement during breathing and activate the radiation beam only when the body is in a certain position.
