SBRT
Also written as: SBRT — Stereotactic Body Radiation Therapy
Highly precise radiation technique delivering large doses in few fractions to small, well-defined targets.
Full Definition
Stereotactic Body Radiation Therapy is a specialized external beam radiation technique that delivers high doses of radiation with extreme precision in typically 1-5 fractions. SBRT uses advanced imaging, patient immobilization, and precise beam delivery to treat small, well-defined tumors while minimizing dose to surrounding normal tissues. It is commonly used for early-stage lung cancers, liver metastases, and select primary tumors.
Usage
Usage note: Also known as SABR (Stereotactic Ablative Body Radiotherapy) in some regions.
