Stereotactic Radiosurgery Program

KU Stereotactic Radiosurgery Program

Stereotactic Radiosurgery is a form of radiation therapy that operates by directing highly focused beams of ionizing radiation with high precision to a small target. The concept of focusing radiation is to diminish the amount of radiation exposure of normal brain tissue while the area of interest receives the necessary coverage. Stereotactic radiosurgery is often used to slow down the growth of small, deep brain tumors. It can also be used to treat arteriovenous malformations.  

Under the direction of Timothy Stepp, MD, the department works very closely with radiation-oncologists and medical physicists. The University of Kansas Hospital uses the Novalis Radiation System.  


This form of treatment is particularly appealing when surgery is considered risky due to the location of the lesion (for example deep seated mass in a critical location of the brain) or due to serious medical conditions (such as elderly or very sick patients) making surgery not an option.

Radiosurgery can also be used as an adjunct for surgery for the treatment of residual or recurrent disease. The procedure is usually performed on an outpatient basis. A specialized mask is fitted and used for the treatment session. Occasionally, a frame is attached for the treatment.
