Treatment process
Step 1: Patient consultation
Physician and patient meet to determine the CyberKnife® System treatment objectives.
Step 2: Patient preparation
CyberKnife® is a completely frameless treatment system.
Fiducial Placement - Patients undergoing CyberKnife® treatment for a prostate or some other, extra-cranial(non-head)lesion, may require a short outpatient procedure to implant several small metal markers (fiducials) near the tumour to enable the CyberKnife® System to track tumour position throughout treatment. Lesions in the head do not require this step.

Making a Mask or Body Mould - A custom made mask (for head/neck treatments) or body mould is formed
and used to help minimize movement during the treatment and ensure your comfort. The process is simple and painless.
Step 3: Image acquisition
Prior to the procedure, a CT scan is performed. The scan is used to identify the exact size, shape and location of the tumour along with the surrounding vital structures to be avoided. Additional scans like MRI, PET CT/angiography may also be done if necessary.
Step 4: Planning
he image is then digitally transferred to the CyberKnife® System’s workstation, where the treatment planning begins. Here, a qualified team uses the CyberKnife® software to generate a treatment plan. Planning of the treatment is one of the most critical and time- consuming process where all the specialists participate (Radiation Oncologist, Other Clinicians,
Physicist, and the radiologist will all participate). The machine itself is under regular quality control, under the care of specially trained physicists. An individual plan of dose delivery will be generated which will maximize the treatment efficacy and minimize the risks involved.

The treatment plan will undergo a dosimetrical verification test.
Step 5: Treatment
Once the treatment plan is developed, the CyberKnife® procedure is set to begin. The CyberKnife® System’s computer-controlled robot will slowly move around the patient, to the various locations from which it will deliver radiation to the tumour.

Each treatment session will last between 30 and 90 minutes, depending on the type of tumour being treated.

If treatment is being delivered in stages the patient will need to return for additional treatments over several days. In majority of cases, patients can resume their previous activities after the completion of the CyberKnife® treatment. However the consultant will give the final advice regarding this.
People after the CyberKnife® treatment will have to undergo follow-up monitoring without fail. The team works out an appropriate set of follow-up tests to provide the patient with more realistic and objective answers

Follow-up imaging, generally performed with a combination of CT, MRI and/or PET scanning, is usually performed in the months following treatment to assess the tumour’s response to the delivered radiation.
