The
CyberKnife® is a state-of-the-art, radiotherapy equipment for robotic
radiosurgery that allows radiation
oncologists to treat pathologies 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 with the help of a robotic
arm. The system tracks the tumour's position, detects any
movement of the tumour or patient, and automatically corrects radiation
delivery.
It
then targets the tumour with multiple beams of high-energy radiation,
destroying abnormal tissue without damaging surrounding areas... cyberknife

How
CyberKnife® works
CyberKnife®
gives patients new hopes for treatment of tumours previously labeled as
inoperable or untreatable. As mentioned earlier, the CyberKnife® uses pencil
beams of radiation, that can be directed at any part of the body from any
direction, via a robotic arm. The vast array of different angles/trajectories
from which pencil beams of radiation converge upon the tumour lead to a high
cumulative dose of radiation at the convergence point (the target/tumour), and
yet a very fast 'fall-off' of dose towards the periphery of the carefully
mapped target. The surrounding normal tissues/organs only receive a small
fraction of the high dose to the target... List of

CyberKnife®
with Synchrony
The
Synchrony system is an additional, enhanced system that works along side the
CyberKnife® System. According to Accuray (the manufacturer of CyberKnife®), the
Synchrony system is the first technology in the world capable of delivering
radiosurgery to tumours affected by the respiratory cycle. This includes
tumours of the lungs, liver, kidney and pancreas. Cyberknife
India
Synchrony uses a complex
system of cameras, motion tracking software,
fibre-optic sensing technology, infrared emitters and a special tight-fitting
elastic patient garment. As a patient undergoes CyberKnife® treatment the
synchrony system continually identifies patient breathing movement in
conjunction with the internally placed fiducial markers and then updates the
treatment delivery of the radiation beams...
How
is CyberKnife® different
Standard
stereotactic radiosurgery techniques rely on a rigid frame fixed to the
patient's skull for head immobilization. There are other systems for
extra-cranial Stereotactic Radiation. These systems are most often
uncomfortable. If the target moves with the breathing of the patient, they
often require breath holding techniques, which may be difficult for some
patients. Frame-based systems mean there is a limit to the number of angles the
radiation can be delivered through...
