Being a pain free non-invasive radiosurgery, CyberKnife significantly reduces the treatment time and treats the affected areas with great accuracy with minimal side effect and helps the patient return to normal. CyberKnife efficiently treats tumours with a pinpoint accuracy through dynamic motion tracking and results in fewer complications as compared to open surgery.
CyberKnife targets the affected area, thus automatically correcting any movements made by the patient or the tumour. Unlike conventional radiotherapy, CyberKnife uses the skeletal structure of the body (rather than invasive metal frames and skull pins) as a reference point for identifying the tumour’s position throughout the treatment. This allows the patient to settle comfortably during the treatment. The duration of the treatment is reduced from 5-6 weeks to a maximum of 5 days with one session per day lasting for about 30-90 minutes. Since the treatment can be performed as an outpatient procedure the patients can immediately return to their normal routine after the session is over.
Since the CyberKnife treatment works with a high degree of precision, there is a minimal possible exposure to the healthy cells by radiation. CyberKnife can treat any inoperable tumour anywhere in the body with pinpoint accuracy and is unmatched when it comes to accuracy. The system can essentially target only the affected area, sparing surrounding healthy tissue, minimising painful side-effects. Multiple beams of high-energy radiation can be delivered from up to 1200 angles to converge precisely on the tumour or lesion.
CyberKnife works on a real-time image guidance software and continually tracks and adjusts to movement during the treatment. Once the location of the tumour is confirmed, it treats lesions that move with respiration (such as lung and pancreas tumours). This allows the doctors to treat even small areas accurately and helps the patient to breathe and relax throughout the procedure.
