What is Stereotactic Body Radiotherapy?

Stereotactic Body Radiation Therapy (SBRT) is the same special form of radiation therapy as SRS, but it is referred to as SBRT when it’s used to treat tumors and other conditions in the rest of the body. Because the technologies used for SRS enable physicians and technicians to focus delivery accurately within millimeters, precise doses of radiation are delivered directly and only to the targeted area. The total dose is often divided into two to five sessions, called fractions.

What can SBRT be used to treat?

SBRT can be used to treat primary and secondary malignancies and benign tumors of the:

  • Spine
  • Brain
  • Adrenal Gland
  • Lung
  • Kidney
  • Pancreas
  • Prostate
  • Liver
