Abstract:
Charged particle radiation is one of the most precise approaches for external radiation right now. With a characteristic inverted depth?dose profile and a high?dose Bragg peak at the end of the range, charged particle radiation therapy can deliver a high dose of radiation to tumor without damages in tissue around the tumor. However, a shift of Bragg peak would result in severe consequences. Therefore, it is extremely important to monitor the radiation beam. Application of position emission tomography ( PET) in proton and heavy?ion radiation therapy makes it possible to get accurate radiation range and position of the particle beam, which improves the treatment accuracy of charged particle therapy. This paper introduces the current application of PET in position verification of charge particle range radiation therapy.
