CyberKnife Center of Central Germany - Team

Personal information


Since 2012, the CyberKnife Center of Central Germany has been treating benign and malignant tumours in all body regions as well as selected other diseases using CyberKnife technology at the Helios Clinic in Erfurt.

The painless and completely outpatient treatment is performed with highest precision by using the CyberKnife device and impairing patients only minimally or not at all. Based on strict criteria, the doctors of the CyberKnife Center determine whether and how radiosurgical treatment is applied.

CyberKnife – the “Invisible Scalpel”

‘CyberKnife’ is a radiosurgical instrument developed in the US. With the CyberKnife, photons from a linear accelerator are directed at the target tissue by a freely movable robotic arm while treatment is guided by an image. This means, possible movements are registered in continuous real-time imaging and the robotic radiotherapy can be adjusted accordingly. High-resolution imaging is required for planning the therapy. Based on this fact, an individual radiation plan is determined for each patient, taking into account size, shape, and position of target tissue cells as well as surrounding structures to be protected.

Advantages of the CyberKnife Process

  • Outpatient therapy
  • Painless and non-invasive
  • Availability of treatment options for patients considered to be beyond a cure
  • Possibility of re-radiation and treatment of radiation-insensitive tumours
  • Low complication risk
  • Short treatment duration
  • Immediate return to the rhythm of everyday life

Treatment Spectrum and Requirements

With CyberKnife, both benign and malignant tumours can be irradiated when appropriate, in addition to specific diseases in almost all regions of the body. Therefore, this method can be a non-invasive alternative or supplement to other therapies and sometimes, it can be a new treatment option. The technology ensures an extremely high precision output, so even difficult-to-reach areas are radiated with maximum accuracy, thus protecting surrounding healthy tissue as much as possible.

A prerequisite for the applicability of CyberKnife radiosurgery is for treated areas not to exceed a particular size and number. In addition, affected regions must be easily distinguished from healthy tissue. Aspects related to the patient and his particular situation come into play as well. For example, these conditions are fulfilled, if surgery or conventional radiotherapy is generally not possible or sensible for the patient. The explicit patient’s wish may also be a criterion for the CyberKnife therapy alternative.

Precision Radiotherapy in Head and Body

  • Radiosurgery (RS) is a high precision radiation in sub-millimetre range, usually a one time high ablative dose, followed by a steep dose drop at the tumour margin for highest possible protection of healthy connecting tissue areas. Only in exceptional cases, a safety border needs to be radiated. This highest precision defined for the RS (approx. 0.3 mm) justifies the often criticised term radiosurgery.
  • Ideal for a one-time RS are the smallest possible, sharply defined areas without tumour infiltration into the surrounding healthy tissue.
  • With the CyberKnife, there is no longer any need to screw a stereotactic frame to the head. Radiosurgical treatments can also be performed fractionally with sub-millimetre precision. For this purpose, the term hypofractionated radiosurgery (multisession radiosurgery = msRS) was established.
  • The CyberKnife can be trained for individual breathing with the so-called "tracking” in order for even moving tumours to be radiated precisely with a lower safety margin.
  • The CyberKnife locates findings to be treated (target volume) with sub-millimetre precision. This accuracy is monitored in real time during treatment and corrected if necessary.
  • Relevant is not only the technical equipment but also the experienced interdisciplinary team continuously working together and training new employees on a long-term basis. As a result, radiation therapists, medical physicists, and neurosurgeons can increasingly learn from each other for the patient’s benefit. In Erfurt, this situation has been going on for 20 years now.

Einsatzfelder Cyberknife

The Tumour Board

The doctors of the CyberKnife Center of Central Germany assess the radiological images and the medical history in advance. If treatment with CyberKnife is considered, a personal on site consultation and information session will follow. Opportunities and risks are explained, and questions are answered.

More specifically, tumours and metastases in brain and base of skull, spinal cord, as well as many different internal organs can be treated with the CyberKnife device. Additionally, benign arteriovenous malformations (congenital vascular malformation in the head region) and trigeminal neuralgia (pain syndrome of the face) can be cured.

CyberKnife Center of Central Germany – a Holistic Concept

In Erfurt, treatment and care is provided by a team of radiotherapists, specialized neurosurgeons, medical physicists, and medical-technical radiology assistants. Through the integration with the Helios Clinic Erfurt, cooperation with local specialists, interdisciplinary exchange, and transfer to other specialist departments, if necessary, is possible.
