CyberKnife:

 

It is the world's first non-invasive whole body robotic radiosurgery system available at HCG. CyberKnife offers patients new hope for the treatment of tumours and lesions, including ones that previously have been diagnosed as inoperable or untreatable with the existing technology. CyberKnife uses state-of-the-art real-time image guidance, similar to cruise missile technology, to precisely target tumours anywhere in the body with pinpoint accuracy and delivers high doses of radiation.

 

CyberKnife system features include:

 

Why CK a good treatment option:

First, the CyberKnife System uses image guidance software to track and continually adjust treatment for any patient or tumour 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 tumours in the head, the CyberKnife System has unlimited reach to treat a broad range of tumours throughout the body, including the prostate, lung, brain, spine, liver, pancreas, and kidney.

 

And finally, the CyberKnife System’s treatment accuracy is unrivalled. Its ability to treat tumours with pin-point accuracy is unmatched by other radiation therapy and radiosurgery systems. The CyberKnife System can essentially “paint” the tumour with radiation allowing it to precisely deliver treatment to the tumour alone, sparing surrounding healthy tissue.

 

The CyberKnife Advantage

 

1. Non-invasive and pain-less

 

CyberKnife is a painless, non-invasive approach to radiosurgery that results in fewer complications than open surgery with comparable results

 

2. Treats inoperable tumours

 

Using a fully integrated robotic delivery system, the CyberKnife allows far superior reach and manoeuvrability to previously inaccessible and inoperable lesions such as lesions involving the spine, optic apparatus and pancreas. Robotic flexibility allows for isocentric as well as non-isocentric treatment.

 

3. Pin-point accuracy

 

With sub-millimeter accuracy, concentrated radiation beams, fired from a possible 1,200 distinct targeting positions, are directly administered to the tumour site, minimizing exposure to surrounding healthy tissue

 

4. Significantly reduces treatment time

 

The treatment duration is reduced significantly from about 5-6 weeks to a maximum of 5 days with one session per day, lasting about 45-60 minutes.

 

5. Automatic movement tracking

 

CyberKnife’s image-guided robotic technology continually tracks patient movement and confirms tumour location prior to beam delivery, making it possible to treat lesions that move with respiration such as lung and pancreas tumours

 

6. No need for invasive body or head frame

 

Unlike conventional radio surgical technology, the CyberKnife system uses the skeletal structure of the body, rather than invasive metal frames and skull pins, as a reference point for identifying the tumour position throughout the treatment.

 

7. Higher radiation dose possible

 

Many patients who previously reached the lifetime dose limit of traditional radiation therapy to critical structures/tissues can receive additional treatment with CyberKnife because of its targeted treatment precision.

 

8. Little or no recovery time

 

Patients can return immediately to their normal routine after the session is over. The treatment can be performed as an outpatient procedure.

 

9. Minimises side effects

 

Since CyberKnife targets only the affected areas with a high degree of precision, there is minimal possible exposure to healthy cells by the radiation. Hence, side effects are minimised.

Cyberknife Technology

 

CyberKnife: How it works

 

A technology that's used for cruise missiles is now being used to fight cancer. CyberKnife relies on image-guided robotic technology.

 

CyberKnife uses two cameras and infrared technology to continually adjust where it is sending the radiation.

 

It checks the position of the tumour, checks the position of the patient, adjusts for any movement -- patient movement or tumour movement and then delivers the treatment accurately.

 

Unlike conventional radio surgical technology, the CyberKnife system uses the skeletal structure of the body, rather than invasive metal frames and skull pins, as a reference point for identifying the tumour position throughout the treatment.

 

The device allows radiologists to use higher doses of radiation without fear of damaging healthy tissue or causing uncomfortable side effects for cancer patients. Concentrated radiation beams, fired from a possible 1,200 distinct targeting positions, are directly administered to the tumour site.

 

Just like a surgeon's knife would just treat the tumour and go around the tumour alone, CyberKnife radiation just focuses on the tumour itself.

 

CyberKnife is allowing doctors to treat tumours in hard-to-reach places like the brain, lungs, liver, prostate and spine.

 

The computer system is able to tell the robot not only where the tumour is, but where it is in relation to the breathing cycle. It allows the doctors to make very, very small treatment fields because the robot breathes with the patient.
