Stereotactic Radiosurgery (SRS)

Stereotactic radiosurgery (SRS) and stereotactic body radiation therapy (SBRT) apply intense radiation with millimeter accuracy for hard to reach tumors with no anesthesia, minimal recovery time and improved patient comfort.

Sometimes called "surgery without a scalpel", SRS is a non-surgical high precision radiation therapy that uses very high doses of radiation to very small volumes for the treatment of various brain tumors including metastatic tumors, benign conditions and abnormal blood vessel formations.

The Trilogy, a linear-accelerator (Linac) based stereotactic system at The Center for Cancer Prevention and Treatment, offers treatments using frameless and frame-based SRS using cones, and intensity modulated radiosurgery. The system offers an optical positioning system for sub millimeter accuracy and high dose rates for treatment that is up to 75 percent faster than comparable systems for treatment delivery.

SRS can employ a framed or frameless system, sparing the patient from invasive and often painful procedures. When used in conjunction with our high precision image guidance and patient positioning systems, SRS is a safe and effective treatment option for patients.
