SABR / SBRT

Stereotactic Ablative Radiotherapy / Stereotactic Body Radiation Therapy

Stereotactic Ablative Radiotherapy (SABR) or Stereotactic Body Radiation Therapy (SBRT) is emerging as an attractive option for treating cancers in the lung, head and neck, prostate, liver and other disease cites outside the CNS. SABR / SBRT is a non-invasive treatment procedure similar to SRS, except that it deals with tumors outside the central nervous system (CNS). The objective of SABR / SBRT is to escalate the dose to the target lesion and thus to increase local control while limiting dose to nearby critical structures and normal tissue. Some requirements of SABR / SBRT program may include precise localization of the target lesion in the treatment planning process; account for tumor motion due to respiration or other changes in the body; highly conformal dose distribution to the target volume including a steep dose gradient to minimize dose to surrounding healthy tissue sparing; and image-guidance at the time of dose delivery for verification and adjustment of the target localization.

Designed to treat targets using sub millimeter mechanical accuracy of the couch, collimator, and gantry, Varian’s linear accelerators dynamically synchronize imaging, patient positioning, motion management and treatment delivery. These versatile, high-performance treatment devices---including the TrueBeam system, Trilogy and Clinac series linear accelerators---can be used for many forms of radiation therapy modalities.
