Proton Therapy Verification with PET Imaging
Proton therapy is very sensitive to uncertainties introduced during treatment planning and dose delivery. PET imaging of proton induced positron emitter distributions is the only practical approach for in vivo, in situ verification of proton therapy. This article reviews the current status of proton therapy verification with PET imaging. The different data detecting systems (in-beam, in-room an...
متن کاملProton dose monitoring with PET: quantitative studies in Lucite.
The feasibility of using PET for proton dose monitoring is examined here in detail. First experimental studies in a Lucite phantom have been performed at the medical TRIUMF proton beamline for proton energies of 62 MeV and 110 MeV. The proton dose delivered to the phantom ranged from 16 Gy up to 317 Gy. The induced activity was analysed 20-40 min after the irradiation with a PET scanner. The ob...
متن کاملThe role of PET in monitoring therapy
Positron emission tomography (PET) is being increasingly used for the evaluation of patients with known or suspected cancer at all phases of the management process from diagnosis, through staging to follow-up after treatment. The role of PET in therapeutic monitoring is expanding rapidly due to its ability to provide earlier and more robust identification of non-responders than provided by conv...
متن کاملConsider potential of gold nanoparticles with proton therapy compared with KV and MEV X-ray therapy.
Introduction: Many study shown the effectiveness dose enhancement with gold nanoparticles (GNPs), especially with low-energy x-rays. Recently, proton beam radiation therapy (PBRT) has attention as a treatment for tumors. The advantage in PBRT, which releases high dose at the controllable Bragg peak position that localized for Au target and the released dose increased in depth....
متن کاملExperimental investigations on in-beam PET for proton therapy
Following the promising results of [1], further phantom experiments have been performed at GSI in order to address the feasibility and accuracy of in-beam positron emission tomography (PET) for proton therapy. For the most challenging issue of range monitoring it has been demonstrated for mono-energetic as well as for spread-out Bragg peak (SOBP) irradiation that range differences of about 0.9m...
