All about Cyberknife

Precise radiation in a nutshell

The CyberKnife® system is a robot-controlled, radiosurgical and, above all, non-invasive treatment method for cancerous tumor diseases in which radiotherapy is planned. It offers the possibility to be used on the entire body such as the prostate, lungs, brain, spine, head and neck, liver, pancreas and kidneys. A treatment consists of 1-5 sessions and offers an outpatient option. The CyberKnife® System has over two decades of clinical experience and has helped thousands of cancer patients.

Benefits of CyberKnife® treatment

Due to the advanced method and technology, the system offers many advantages at one
conventional radiation. Since it enables a pinpoint and precise irradiation,
surrounding tissue and neighboring organs are spared and side effects minimized.
CyberKnife® technology enables above-average treatment success. through the
outpatient treatment, you can quickly return to active life.

Benefits summarized


  • outpatient rather than inpatient treatment
  • non-invasive and painless treatment
  • no fixation in a fixed frame
  • Alternative to open surgery
  • Alternative to conventional fractionated radiotherapy
  • no anesthesia or sedation
  • no increased risk due to age or comorbidities

What can be treated with Cyberknife?

A large number of tumors and metastases can be treated with the CyberKnife method. The focus is, for example: brain diseases, lung diseases, liver diseases, diseases of the prostate, the spine, as well as lymph and kidneys. Depending on the location, the lesion to be treated should not exceed a certain size and should be clearly delimitable on image materials. Do you have a direct question about a specific treatment area? Which one are you interested in?

Brain diseases

A large number of benign and malignant brain tumors can be treated with the CyberKnife® technology.

Lung diseases

Small and well-defined lung tumors can be treated non-invasively with single-stage radiosurgery

Spinal diseases

Benign and malignant spinal tumors represent a suitable indication for CyberKnife® treatment.

Lymph node disease

In certain locations, individual lymph node metastases can be treated with the Cyberknife technology.

Liver disease

Liver metastases and hepatocellular carcinomas have been successfully treated with the CyberKnife® method for years.


Pancreatic disease

The CyberKnife® method is a low-risk and gentle treatment alternative for pancreatic tumors.

Renal disease

As an alternative to surgery, renal cell carcinomas can be successfully removed using CyberKnife® treatment.

Prostate disease

As an alternative to surgery or conventional radiation, certain prostate carcinomas can be treated well with the CyberKnife® method.

Bone disease

In advanced stages of the disease, CyberKnife® treatment is a safe option for pain relief in bone metastases.

The technology

The linear accelerator

The core is the linear accelerator, which is mounted on a six-axis industrial robot from KUKA. In this way, the irradiation head can be flexibly controlled.

Continuous position control

The image location system consists of two X-ray tubes mounted on the ceiling and two image detectors embedded in the floor. These are aligned at a 90 degree angle to each other and ensure optimal reproducibility of the storage.

Respiration compensation

With respiratory compensation, the movement of the tumor can be compensated. To do this, LEDs are attached to the upper body and their movement during the entire irradiation of a
camera is recorded. The surrounding tissue is protected as much as possible.
