Treatment Procedure
Scanning: Prior to the treatment with CyberKnife® System, the patient undergoes imaging procedures, which may include CT/MRI/PET CT, to determine the exact size, shape and location of the tumour. The CyberKnife® Treatment Planning Software helps to integrate CT scans and other imaging data into the pretreatment planning process.

Planning: After scanning, the image data are then digitally transferred to the CyberKnife® System’s dedicated treatment planning workstation, where the treating physician identifies the exact size, shape and location of the tumour to be targeted and the surrounding vital structures to be avoided.

A qualified physician and/or radiation oncologist or physicist then uses the CyberKnife® software to generate a treatment plan to provide the desired radiation dose to the identified tumour location. As part of the treatment plan, the CyberKnife® System’s proprietary planning software automatically determines the number, duration and angles of the delivery of radiation beams.

Treatment: A patient lies comfortably on the treatment table during the CyberKnife® procedure. Anesthesia is not required, as the procedure is painless and noninvasive.

The treatment, which generally lasts between 30 and 90 minutes, typically involves administration of about 100 to 200 radiation beams delivered from different directions, each lasting 10 to15 seconds. Prior to the delivery of each radiation beam, the CyberKnife® System simultaneously takes a pair of X-ray images and compares them with the DRR generated from the planning system.
