Proton Therapy

Eye tumour therapy success story


Set-up for irradiation of biological samples with very high dose rates (FLASH).


A publication from the ATT team is highlighted by the editors of the journal "Medical Physics" as recommended reading. It concerns the so-called FLASH therapy, which the team tested on mouse eyes: in this case, the tumour is irradiated with protons only very briefly, but very strongly. This FLASH therapy also destroys the tumour, but has fewer side effects.

The ATT team is developing a diagnostic system to precisely determine the energy and range of the proton beam. The company DE.TEC.TOR. S.r.l. acquires the licence to market the invention as a certified medical device. It ensures the quality of eye tumour therapy.

There is a pre-accelerator for the generation and initial acceleration of the protons. Now an additional pre-accelerator is being built. A so-called "tandetron". When the tandetron is serviced, the original pre-accelerator takes over and ensures the availability of the therapy.  



In December 2007, we welcome the 1000th patient for whom we were able to successfully perform radiotherapy.

On 22 June 1998, the first patient is treated with proton therapy.

Therapy room for proton therapy at the Wannsee site. In this room, patients are prepared for proton therapy and are and later irradiated.
