Proton centre

PARTICLE is a high-technological centre for proton therapy.

Thanks to a different radiation technique, tumours can be radiated more accurately.

In addition to treating cancer patients, the centre also researches the further development of proton therapy.

How does proton therapy work?

Proton therapy

Proton therapy is an innovative type of radiotherapy that uses proton beams instead of a photon beams (X-rays) such as in classic radiotherapy.

How does it work?

Proton therapy uses a bundle of proton, positively charged particles, which originate from the core of an atom, and which only emit their maximum dose when reaching a certain depth in the body, after which radiation completely stops (in contrast to photons).

What are the benefits?

The main benefit of proton therapy with respect to the current photon therapy is that healthy tissue behind the tumour can be spared as much as possible, reducing the global radiation load in case of treatment with protons.

Who qualifies?

Proton therapy is not the most suitable radiation technique for all tumours. The patient's age, the type of tumour, the size and shape of the tumour, the localisation and the position in relation to the surrounding healthy tissue strongly determine the benefit of protons.

Referral procedure

Information for referring physicians about which patients qualify for proton therapy, how the application needs to be submitted and information on follow-up during and after treatment.


The supplier of the proton therapy device is IBA. This Belgian company is the worldwide technological leader in the field of proton therapy. The device that has been installed in the clinical bunker is the Proteus®ONE: a compact device that left sufficient room for a second bunker specifically for research.

The building

The new proton centre is an important project in the medical world; a national and international leading institute. The essence of the design of the building was to be able to provide this high technological form of radiation to the patient in high-quality and safe manner.

Collaboration proton centre PARTICLE

The Particle Therapy Interuniversity Centre Leuven – or PARTICLE for short - is an interuniversity project of the University Hospitals Leuven - KU Leuven and Cliniques universitaires Saint-Luc ∙ UCLouvain, supported by UZ Gent, CHU UCL Namur, UZ Brussel and UZA

Scientific research

The proton therapy centre includes 2 areas, also called bunkers. One is used for the treatment of patients and clinical research, the other for more applied preclinical research.
