Description
It has been demonstrated [1] that PET information can be used successfully for
online monitoring of particle range as well as for dose quantification in both proton
and carbon therapy . Furthermore, it is clear that PET [1] is the only issue today
for an in-situ and non-invasive treatment plan monitoring. However, existent PET
systems are designed either for diagnostics or functional medical imaging where the
emitters are injected in sufficient amounts to cope with the low sensitivity of the
detectors. In hadrontherapy, the activity is due to rather short-lifetime target or
projectile nuclear fragments like C, C or O. Thus, the activity is about two
orders of magnitude lower than the corresponding activity in conventional PET
imaging. The development of new efficient PET detectors dedicated to hadrontherapy
becomes crucial.
In this talk, after a brief description of PET requirements in hadrontherapy, we will
describe our R&D activities dedicated to online plan control with PET in
hadrontherapy. I will also present some preliminary results obtained with our
prototype in real beam conditions.
