Unlike conventional radiation therapy, which delivers low dose radiation in 30 to 45 treatments, Cyberknife radiosurgery delivers high dose radiation in as few as one to five treatments. The Cyberknife system can be used by itself as an alternative to surgery and is also sometimes used following surgery.
The Cyberknife system is unique because it has the ability to automatically correct treatment delivery for even the slightest movement in the tumor or the patient. This ability is important for treating tumors that move, particularly those in the spine, lung, liver, pancreas and prostate.
As an example, a lung tumor moves constantly while the patient breathes. With conventional radiation, oncologists have to radiate the whole area where the tumor might be during any phase of respiration. With the Cyberknife, the radiation device actually tracks the tumor and allows it to give a very focused dose of radiation to the tumor, not the surrounding, healthy lung tissue.
The Cyberknife literally can move around the room to provide high dose radiation to any area of the body with total precision. It can come from any angle to the patient.
Unhindered by the clockwise, counterclockwise constraints of traditional radiation systems, the Cyberknife system’s robotic mobility has significantly improved dose sculpting capabilities and dose distributions.
