What is the CyberKnife® system?

The robot-assisted CyberKnife® radiosurgery system is a tried-and-tested alternative to the operative treatment of tumors in all body regions.

Course of treatment

The course of treatment normally includes four steps:

A modern CT Scanner

A modern CT Scanner

Computer tomographic scanner

Prior to treatment, the size, shape and position of the tumor must be specified by digital imaging methods. This process starts with a high-resolution CT scan, whilst other digital imaging methods, such as MRI, angiography or PET scan, are used to map special tumors.

Treatment planning

After CT scanning, all the digital images are transmitted to the treatment planning workstation where the treating physician identifies precisely the size, shape and position of the tumor.

Using our CyberKnife® software, one of our seasoned physicians sets up a treatment plan for delivering the necessary radiation doses to the tumor position identified without damaging the surrounding healthy tissue. The patient’s presence is not required during this treatment step.

Treatment is comfortable for patients.

Treatment is comfortable for patients.


During CyberKnife® radiation treatment, patients lie comfortably on the treatment table and are automatically positioned. Since radiation is painless and non-invasive, no anaesthesia is necessary. Treatment normally takes between 30 to 90 minutes usually involving one to five sessions.


In order to evaluate tumor reaction to the radiation doses administered, after-care includes a check-up involving a digital imaging method (CT, MRI or PET scan) and this usually takes place in the months following treatment.
