About Cyberknife

What is a Cyberknife S7 Robotic Radiation Therapy ?

The Cyberknife S7 Robotic Radiation Therapy System is a non-invasive alternative to surgery for the treatment of both cancerous and non-cancerous tumours in the (prostate, lung, brain, spine, liver, pancreas, and kidney) and non cancerous tumors. The therapy, which delivers high-dose radiation beams to tumours with pinpoint accuracy, gives patients around the world new hope.

Although the name conjures up images of scalpels and surgery, the CyberKnife S7 treatment does not involve any cutting. In fact, the CyberKnife S7 System is the world's first and only Robotic Radiation Therapy system designed to treat tumours throughout the body non-invasively. It offers a painless, non-surgical option for patients with inoperable or surgically complex tumours, as well as those seeking an alternative to surgery.

In this technology, a robotic arm is used to focus the radiation rays with any part of the body. A Lightweight Linear Accelerator, abbreviated as LINAC, is used in conjunction with a Robotic arm to provide views from various angles.

What makes Cyber knife S7 Unique

  • Unrivaled accuracy: The CyberKnife S7 system can treat moving tumours with pinpoint accuracy that other radiation therapy systems cannot match. This is especially important when treating tumours that move in response to any bodily function (e.g., breathing).
  • Unrestricted flexibility and freedom: The robotic maneuverability of the CyberKnife S7 system enables doctors to deliver highly personalized treatments. CyberKnife S7 clinicians at Valentis can select various angles targeting the tumour with a high dose of radiation from every conceivable angle using a linear accelerator mounted on a flexible robotic arm.
  • Real-time image guidance: The CyberKnife S7 employs a sophisticated 6D image guidance system to track and adjust treatment in response to any movement of the patient or tumour.
  • Convenient: Depending on the type of tumour, patients typically require one to five CyberKnife S7 treatments, which typically last less than 30 minutes, whereas other radiation systems require dozens of treatments spread out over several weeks.
  • Patient safety: The CyberKnife S7 is a fully integrated closed-loop system, unlike other gantry-based linear accelerators. Each function collaborates to provide the safest possible patient experience.

Getting Ready for Cyberknife S7


Following a diagnosis, Valentis doctors team may recommend CyberKnife S7 treatment based on the patient's specific needs. A team of Valentis doctors, including radiation oncologists, medical oncologists, and surgeons, as well as medical physicists, radiation technicians, and nurses, collaborate to develop the patient's care plan.

Imaging and treatment planning

Prior to beginning treatment, an MRI, CT, or CT/PET scan is performed to determine the size, shape, and location of the tumour. The images from these scans are digitally transferred to the CyberKnife's treatment planning workstation, where Valentis specialists identify the tumour to be targeted and the vital structures surrounding it to be protected. The strategy is intended to match the desired radiation dose for the tumour while limiting exposure to surrounding healthy tissue.

Fiducial placement:

Fiducials (small golden markers) are inserted to determine the exact location of the tumour, depending on the type and location of the tumour.
