CyberKnife® Radiosurgery
What is CyberKnife® Radiosurgery?
CyberKnife radiosurgery is a precise, painless, non-invasive radiation treatment that can be an alternative to open surgery in certain cases. Multiple beams of high-energy radiation are delivered from multiple points and converge precisely at the tumour or lesion inside the body.
Each individual beam is insufficient to cause harm, but the convergence of all the beams at the tumour results in the lesion receiving a very high dose of radiation whilst sparing nearby normal tissue.
Each individual beam is insufficient to cause harm, but the convergence of all the beams at the tumour results in the lesion receiving a very high dose of radiation whilst sparing nearby normal tissue.
CyberKnife radiosurgery is so precise that radiation beams can be sculpted to small, complex-shaped tumours near critical structures, such as hearing and vision nerves. This ability to irradiate the tumour accurately and to protect healthy tissue allows the CyberKnife to treat many lesions which may be considered inoperable or untreatable without this radiosurgery system.
How does CyberKnife work?
CyberKnife is a revolutionary way of performing stereotactic radiosurgery and it combines two advanced technologies.
The second innovation is the image guidance system. This allows the CyberKnife to locate and track the tumour throughout the treatment, correcting for small patient movements.
The first innovation is a lightweight radiation delivery system, mounted on a multi-jointed robotic arm. The robotic arm provides unparalleled access to tumours anywhere in the body. It reaches areas that are untreatable with other radiosurgery systems and allows more flexible delivery of radiation from different angles, for optimum treatment.
What makes CyberKnife so unique?
100% Frameless
The ability of the CyberKnife to correct for patient movement during treatment spares you from the pain and inconvenience associated with a conventional head frame that must be fixed to the skull with screws. Published studies have shown that the frameless CyberKnife radiosurgery is as accurate - if not more so - than traditional frame-based radiosurgery.
'Full body' capability
The unique design of the CyberKnife system allows it to deliver precise, high dose radiation not just to lesions in the brain but to lesions in the spine and to other organs. The various organs of the body respond differently to radiation treatment, so special protocols have been developed for different types of tumour. As this work continues at individual CyberKnife® centres around the world, so the range of CyberKnife treatments available has increased.
Because no frame is required, CyberKnife can perform “hypo-fractionated” or staged radiosurgery - where the total radiation dose is divided into smaller doses delivered over a period of days. This is especially beneficial for treating lesions near sensitive structures and larger tumours because it better protects surrounding healthy tissue.
Staged treatment
Painless
CyberKnife allows you to be treated in a unique radiosurgery suite where painless “surgery” is performed, eliminating the risk of complications and lengthy recovery time associated with traditional open surgery.
Better quality of life, during and after treatment
The CyberKnife procedure allows you to resume normal activities immediately after treatment.
