Abstract
Hadrontherapy is a technique that uses accelerated charged ions for cancer treatment. The high irradiation precision and conformity achievable during hadrontherapy treatments allows for local tumor control and sparing of the surrounding healthy tissues. Such a high spatial selectiveness requires the development of new dose monitoring techniques. It has been proved that the beam emits secondary particles in the path to the tumor, namely γ from β+ emitters, prompt γ from nuclear de-excitation and charged particles, that can be used to monitor Bragg Peak (BP) position and the related dose release. In this contribution preliminary results obtained in the study on the neutral and charged secondary particles produced by 12C, 4He and 16O ion beams of therapeutical energy impinging on PMMA phantoms will be presented. The data acquisition have been performed at GSI (Darmstadt, Germany) and HIT (Heidelberg, Germany) facilities. A correlation between the secondary generation regions and BP position will be shown and the design of a monitoring device exploiting all the secondary information will be outlined.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
