About CyberKnife
The CyberKnife is not actually a knife at all. It's a state-of-the-art piece of equipment that allows specialist physicians  to treat tumours and other medical conditions painlessly without the need for an operation.
 
 
CyberKnife uses pencil beams of radiation which can be directed at any part of the body from any direction via a robotic arm. The robotic arm tracks the tumour's position, detects any movement of the tumour or patient, and automatically corrects its positioning before targeting the tumour with multiple beams of high-energy radiation, destroying abnormal tissue without damaging surrounding areas.
 
The treatment is so accurate that it's now possible to treat tumours previously thought to be inoperable. Although the results of treatment do not always show immediately, in most cases the procedure will initially stop the growth of tumours before gradually reducing their size.
 
As there is no open surgery, the complications normally associated with an operation are eliminated, as is the need for a long recovery time. This makes treatment suitable for those who are not well enough to cope with the side-effects of surgery and most patients leave the clinic the same day as their treatment.

The advanced technology also eliminates the need for patients to be fitted with a brace or restraining device during the treatment phase, making the whole procedure less stressful for patients.

The CyberKnife® System is a one-of-a-kind device for several reasons :
 
 
  • First, the CyberKnife System uses image guidance software to track and continually adjust treatment for any patient or tumor movement. This sets it far ahead of other similar treatments. It allows patients to breathe normally and relax comfortably during treatment.

  • Second, some forms of radiosurgery require rigid head-frames that are screwed into the patient’s skull to minimize any movement. The CyberKnife System does not require such extreme procedures to keep patients in place, and instead relies on sophisticated tracking software, allowing for a much more comfortable and non-invasive treatment

  • Third, unlike some radiosurgery systems, which can only treat tumors in the head, the CyberKnife System has unlimited reach to treat a broad range of tumors throughout the body, including the prostate, lung, brain, spine, liver, pancreas, and kidney.
 
 
And finally, the CyberKnife System’s treatment accuracy is unrivaled. Its ability to treat tumors with pin-point accuracy is unmatched by other radiation therapy and radiosurgery systems. The CyberKnife System can essentially “paint” the tumor with radiation allowing it to precisely deliver treatment to the tumor alone, sparing surrounding healthy tissue
 
 
How the CyberKnife works  
 
The vast array of different angles/trajectories from which pencil beams of radiation converge upon the tumour lead to an extremely high cumulative dose of radiation therapy at the convergence point (the target/tumour) and yet a very fast 'fall-off' of dose at the periphery of the carefully mapped target. The surrounding normal tissues/organs only receive a small fraction of the high central dose of therapy.
 
Whilst any tumour may be destroyed by a very high dose of radiation therapy, it has very often been the case, with orthodox radiotherapy, that it has not been possible to deposit the required dose on a tumour without also depositing a toxically high dose of radiation on the surrounding organs. Cyberknife often overcomes this problem by its capability to so accurately target and achieve a fast dose gradient ('fall-off') at the perimeter of the tumour/target.
   
The CyberKnife® Robotic Radiosurgery System is a non-invasive alternative to surgery for the treatment of both cancerous and non-cancerous tumors anywhere in the body, including the prostate, lung, brain, spine, liver, pancreas and kidney. The treatment – which delivers high doses of radiation to tumors with extreme accuracy
 
 

offers new hope to patients who have inoperable or surgically complex tumors, or who may be looking for a non-surgical option.
