Cyberknife is the world's first and only robotic
radiosurgery system which treats tumours anywhere
in the body without any surgery. Though it is
called Radiosurgery or Cyberknife- No knife is
used for incision and no surgery is performed to
treat the tumours. A new hope for patients who
have inoperable or surgically complex tumors, or
who may be looking for a non-surgical option.
Cyberknife radiosurgery is a non invasive,
high-energy radiation treatment that delivers
very precise beams of radiation from many angles
outside the body. The accuracy of Cyberknife is
so precise that radiation can be 'matched' to the
shape of small complex tumors, even those located
near critical organs. This ability allows
Cyberknife to treat many lesions including some
considered inoperable or untreatable with surgery.

The CyberKnife Robotic Radiosurgery System treats
both cancerous and non-cancerous tumors anywhere
in the body, including the prostate, lung, brain,
spine, liver, pancreas and kidney. It provides
a pain-free, non-surgical treatment to the
patients with complex tumours which are un
operable or too risky to be operated and to the
patients who are looking for an alternative to
surgery. To date, more than 100,000 patients have
been successfully treated and more than 150
systems are installed worldwide.

CyberKnife system consists of an advanced
lightweight linear accelerator (LINAC) - this
device is used to produce high energy 'pencil'
beams of radiation. There is a robot, that can
make the linear accelerator point from a wide
variety of angles. It's movements are under the
control of a central computer. This centralized
computer controlled movement of the system that's
also called as the 'Brain' of the machine A pair
of X-ray cameras are able to obtain frequent
pictures of the patient during the treatment
session. The computer uses this information to
target the radiation beam with sub-millimeter
accuracy.
The Cyberknife accuracy represents a major
advance in radiosurgery. Digital radiographic
images of anatomical features or implanted
fiducials are used to precisely target the
radiation. The focused radiation beams converge
at the tumor to maximize the amount of radiation
that reaches the tumor and minimize exposure
surrounding health tissue.

Advantages of CyberKnife Radio Surgery
The CyberKnife system is able to locate tumors
within the body without the use of an invasive
stereotactic headframe used with other systems.
This is much more convenient and less traumatic
for patients. While other forms of radiosurgery
can only treat tumors in the head, Cyberknife can
treat tumours anywhere in the body- brain, spine,
liver, lungs, pancreas, kidney or
prostrate. While other forms of radio surgery
treatment techniques need rigid head-frames
screwed to the patient's head for controlling
movement, which is painful and cumbersome for the
patient,
CyberKnife 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.
