Proton therapy (PT) exploits the Bragg peak depth-dose profile to obtain conformal treat- ments, while sparing healthy tissues surrounding the tumor. Despite the high physical selectivity, PT is very sensitive to treatment-related uncertainties. Among these uncertain- ties, organ motion acquires increasing importance for pencil beam scanning PT. We will describe a novel device, called 4DPhantom (3D plus time), which is able to reproduce the real breathing signal of oncological patients during proton therapy treatment and can be combined with dosimetric devices for quality assurance purposes.

Abstract

Proton therapy (PT) exploits the Bragg peak depth-dose profile to obtain conformal treat- ments, while sparing healthy tissues surrounding the tumor. Despite the high physical selectivity, PT is very sensitive to treatment-related uncertainties. Among these uncertain- ties, organ motion acquires increasing importance for pencil beam scanning PT. We will describe a novel device, called 4DPhantom (3D plus time), which is able to reproduce the real breathing signal of oncological patients during proton therapy treatment and can be combined with dosimetric devices for quality assurance purposes. The results of the first successful tests, performed at the Centro di Protonterapia di Trento, will also be shown.
