Feasibility of Pulsed Proton Induced Acoustics for 3D Dosimetry
Alsanea, Fahed M. M.S., Purdue University, May 2014. Feasibility of Pulsed Proton Induced Acoustics for Dosimetry. Major Professor: Keith Stantz. Proton therapy has the potential to deposit its energy in tissue with high conformity to the tumor and significantly reduced integral dose to normal tissue compared to conventional radiation, such as x-rays. As a result, local control can be enhanced ...
متن کاملSU-E-T-73: Investigation of 3D Dosimetry for Proton Therapy Using PRESAGE.
PURPOSE This investigation studies the feasibility of PRESAGE, a 3D polyurethane dosimeter, for relative dosimetry measurements of clinically relevant proton treatments using an anthropomorphic head phantom developed by the Radiological Physics Center (RPC). Performance of a low-LET dependent PRESAGE was evaluated by comparison to the traditionally used radiochromic film, EBT2, and thermolumine...

15 صفحه اولPatterns of failure after proton therapy in medulloblastoma; linear energy transfer distributions and relative biological effectiveness associations for relapses.
PURPOSE The pattern of failure in medulloblastoma patients treated with proton radiation therapy is unknown. For this increasingly used modality, it is important to ensure that outcomes are comparable to those in modern photon series. It has been suggested this pattern may differ from photons because of variations in linear energy transfer (LET) and relative biological effectiveness (RBE). In a...
متن کاملReference Dosimetry for Fast Neutron and Proton Therapy
Fast neutrons and protons undergo fundamentally different interactions in tissue. The former interact with nuclei, while the latter, as in the case of photons, interact mainly with atomic electrons. Protons do, however, also undergo some nuclear interactions, the probability of which increases with energy. For both modalities the practical instruments for determining the reference absorbed dose...
