Stereotactic Body Radiation Therapy (SBRT)


One of the first locations in the Sacramento Valley to offer SBRT, UC Davis Comprehensive Cancer Center has provided this high-tech treatment for more than 10 years.

Stereotactic body radiation therapy (SBRT) is a similar procedure to brain stereotactic radiosurgery and radiotherapy (see Gamma Knife), except it is used on tumors outside the brain (extracranial), generally in the lungs, liver and spine. SBRT is an emerging treatment for lung cancer in patients who are not candidates for surgery.

SBRT uses highly accurate imaging to deliver precise, high dose radiation (either in a single dose or in a small number of high-dose fractions) to areas with substantial normal organ motion inside the body. SBRT involves patient immobilization and image-guided radiation therapy (IGRT). The technologically advanced imaging techniques used in this treatment can predict tumor motion and guide the dose to the tumor site, ensuring safe and effective cancer treatment.

The Department of Radiation Oncology uses the new Elekta-S linear accelerator as it safely and effectively delivers highly focal radiation treatments to a larger target.
