The Early years
At the beginning most of the patients have been treated in research facilities, where parasitic beams were devoted for relatively short periods to the treatments. Only in the nineties dedicated based facilities have entered in use.

The Present of Hadrontherapy
Nowadays proton therapy is a mature field, many firms are competing to offer more and more reliable proton facilities and also the production of accelerators for light-ion therapy is rapidly increasing

The Accelerator is a very small part of a PT center
A Proton therapy system is much more than an accelerator It is most often a complex, multi-room treatment systemThe treatments rooms are larger than the cyclotron/synchrotron vault Half of the total investment is for the equipment

Cyclotrons for PT
In the 90’s the consensus was that the best accelerator for PT was a synchrotron However today the majority of the PT centers use the cyclotron technology (IBA, Varian, Still Rivers…)Over these 15 years, users appreciated the advantages of cyclotrons:
Simplicity ReliabilityLower cost and sizeMost importantly the ability to modulate rapidly and accurately the proton beam current
But fixed energy…10-11 June 2009 21IFIMED'09 Symposium
