About CyberKnife

CyberKnife, is one of the most advanced forms of radio-surgery. It is a painless, non-invasive treatment that delivers high doses of precisely targeted radiation to descry tumour or lesions within the body. It is a non-invasive treatment which does not involve surgery or making any incisions.

The difference between CyberKnife and radiation therapy; is that CyberKnife treatment does not require surgery, whereas radiation therapy is often performed on conjunction with surgery. CyberKnife treatment also reduced the amount of radiation therapy used, making theme scale a lot quicker and more efficient.

CyberKnife involves the use of a robotic arm, that has unparalleled flexibility, where the beams of radiation can be directed even at difficult to reach areas of the body. The beams are so precise, they focus only on the tumour and minimise dose to healthy surrounding tissue.

The treatment is typically performed on patients with inoperable tumours or surgically complex tumours, or used as an alternative to surgery.

CyberKnife treatment can be used anywhere in the body such as:

  • Brain
  • Lung
  • Prostate
  • Pancreas
  • Liver
  • Spine



CyberKnife provides several advantages over other radio-surgery systems or conventional ways to deliver external radiation:

  1. It targets tumours perviously considered unreachable by surgery or conventional radiation
  2. It may have fewer complications and lower risks than surgery or radiation
  3. Treatments are typically completed in less time than traditional treatments. CyberKnife usually requires between 1-5 sessions, whereas traditional radiation may require as many as 40 sessions.
  4. It does not require anaesthesia or incisions, hence does not involve blood loss or recovery time.
  5. Other similar techniques require patients to wear uncomfortable frames during procedure whereas, CyberKnife uses the body’s bony structures or implanted markers to find its target.
  6. It is an outpatient procedure where patients usually go home the same day.
  7. Other techniques require patients to  hold their breath during treatment, whereas; CyberKnife uses Synchrony Respiratory Tracking System to follow tumour movement even while you breathe.
  8. It can provide radiation beams on the tumour from more than 1400 different possible angles, allowing concentrated radiation on the tumour itself and avoiding surrounding healthy tissue.
  9. It is a safe and effective treatment for areas that could not be previously treated with radiation therapy hence providing a new option for these patients.
  10. Unlike radio-surgery systems, the dose can be spread over multiple visits, particularly helpful in avoiding damage to critical brain tissues and nerves when treating brain tumours.


CyberKnife is one of the most advanced and effective stereotactic radio-surgery technologies, which is a method of controlling or destroying tumours by aiming beams of radiation at them from multiple directions. Multiple x-ray cameras and powerful software pinpoint the exact location of the tumour. A robotic arm points a liner accelerator directly at the timor from from than 1400 different angles, aiming high powered radiation beams at it.

The patient will be asked to lie down on the treatment bed and the robotic arm from the CyberKnife will rotate around the body. Once the tumour has been detected, the robotic arm will deliver high doses of radiation through beams directed at the tumour, from various angles.

Anaesthesia: No anaesthesia is required, and the patient should not feel pain during the treatment. During the procedure the patient is monitored by doctors from a neighbouring room.

Procedure duration: The treatment usually lasts for 30-90 minutes.
