What is Radiosurgery?

Radiosurgery is a non-invasive procedure that uses precisely directed high-energy radiation beams to destroy abnormal (often cancerous) lesions within the body and brain. Using stereotactic techniques, or 3D targeting, an ablative dose of radiation can be delivered to the lesion while simultaneously sparing the normal surrounding tissues. Due to unparalleled treatment accuracy overwhelming doses of radiation can be delivered to the target in a short overall treatment course. By definition, the entire radiosurgery is administered in one to five daily sessions. This is in stark distinction to standard radiation (even with image guidance) that is generally delivered daily over a 4-8 week time period. Normal tissue, via standard radiation techniques, is exposed to certain amounts of radiation which necessitates the standard treatments to be spread out over time to allow for normal tissue repair. The amount of normal tissue exposed to radiation is greatly minimized by the use of stereotactic radiosurgery.

Advantage of CyberKnife based stereosurgery

Real-time tumor tracking

The CyberKnife allows for unprecedented accuracy in the delivery of very high dose radiation. This is possible due to constant tracking of the tumor during treatment which allows us to minimize the exposure of normal tissues to radiation thereby reducing treatment related side effects.
