Accuracy Assessment of Bragg Peak Imaging Using Protoacoustics at a Clinical Dose

Authors: Michael Caulfield, Ye Chen, Yoshihiro Ishi, Yasutoshi Kuriyama, Taeko Matsuura, Naoki Miyamoto, Taichi Murakami, Tomonori Uesugi, Kohei Yokokawa

Affiliation: Hokkaido University, Kyoto University, University of Alberta

Abstract Preview: Purpose: Protoacoustics has the potential for real-time and direct imaging of the Bragg peak. This study investigated the accuracy of the Bragg peak imaging based on the water phantom experiment at a ...

An Initial Simulation Study Towards the Patient-Specific Estimation of Stopping Power Ratio and Sound Velocity Using Protoacoustics: A Sensitivity Matrix Method

Authors: Ye Chen, Koki Kasamatsu, Taeko Matsuura, Taichi Murakami

Affiliation: Hokkaido University, National Institutes for Quantum Science and Technology (QST)

Abstract Preview: Purpose: In proton therapy, CT-based estimation of the stopping power ratio (SPR) is a significant source of range uncertainty. Protoacoustics have been developed to estimate the range in vivo, but fe...

Feasibility of a Normoxic N-Vinylpyrrolidone-Based Polymer Gel (VIPET) Dosimeter for Three-Dimensional Proton Beam Measurements

Authors: Yoshihiko Hoshino, Kenji Hotta, Taeko Matsuura, Ai Nakaoka, Hidenobu Tachibana

Affiliation: Hokkaido University, Department of Radiology, Gunma University Hospital, Radiation Safety and Quality Assurance Division, National Cancer Center Hospital East

Abstract Preview: Purpose: Gel dosimeters enable three-dimensional dose measurements, but no reports have evaluated the fundamental performance of VIPER-type gel dosimeters in proton beam measurements. Therefore, we ev...
