Those who are diagnosed with a brain tumour (such as acoustic neuroma or meningeoma) usually find themselves and their relatives confronted with a new life situation. Questions about possible treatment options quickly arise. ZAP-X is one of these options and

represents an outpatient alternative or supplement to a classic surgical operation or conventional irradiation – all of which is state-of-the-art in medicine and technology.


Alternative to surgery

ZAP-X offers a promising treatment option without the disadvantages of a classic operation.

Completely painless

Treatment with ZAP-X does not cause pain.

No anaesthesia required

During treatment with ZAP-X anaesthesia will not be performed.

Treatment cycle

Usually only one treatment with ZAP-X is needed. This takes about 30 minutes.

Extremely accurate

ZAP-X can fight tumours such as acoustic neuroma, meningeoma or brain metastases in the sub-millimeter range. This protects healthy tissue.

no head-frame

A frame fixation on the skull is not necessary with ZAP-X.

State-of-the-art technology

With ZAP-X, a so-called turret system selects the required beam diameter according to the treatment plan.

Outpatient procedure

Therapy with ZAP-X does not require a prolonged hospital stay.

Alternative to conventional irradiation

In many cases, ZAP-X can replace conventional radiation therapy that lasts several weeks.


Treatment with ZAP-X is possible in the following head and neck indications:


With its unique gyroscopic freedom of movement With its unique gyroscopic freedom of movement, ZAP-X breaks new ground in modern radiosurgery. It combines the technology of self-shielding with a high radiation dose rate and is the next step in non-invasive tumour treatment.

This is how the ZAP-X treatment process works at ERC Munich.

After the patient has contacted us (in person, via e-mail or by telephone), we at ZAP Munich first need the respective findings, including MRI and CT images, in order to get a picture of tumor or metastasis factors and questions such as:

  • How large is the tumor/metastases?
  • Where is the tumor/metastases located?
  • What form does the tumor/metastases have?


We then check whether the treatment with ZAP-X is appropriate and discuss our results with the patient.

If the case is suitable for treatment with ZAP-X, the available data will be transferred to the computer. Now it is checked:

  • How is the irradiation done?
  • How is the irradiation dosed?
  • What is the best way to protect diseased tissue?

On the day of treatment, there is a brief preparation and briefing for the patient. Then it goes to the treatment, during which the patient is allowed to lie comfortably. On average, treatment with ZAP-X takes about 30 minutes. The patient can leave our centre on the same day – after a final discussion with the treating doctor, of course.

Each tumour responds differently to treatment – just like metastases: Sometimes the disappearance takes a little longer, but the growth may have been stopped immediately. Sometimes already irradiated tissue has to be retreated. Quarter to six months after the treatment, an initial check-up is performed, during which current images from the MRI are viewed.
