With the technologic advancements in image guidance and dose delivery, stereotactic body radiotherapy (SBRT) is being widely used for cancer treatment in various anatomical locations as a noninvasive alternative to surgery. To deliver ablative doses to tumors with limited normal tissue toxicity, SBRT requires high accuracy in treatment setup which requires taking tumor motion into account. Techniques are also applied in SBRT to minimize tumor motion during dose delivery. This paper reviews techniques for motion management in SBRT.
