Outline of Final Research Achievements |
The purpose of this study was to device a new system that reconstructs the real-time dose distribution inside patients to evaluate an accuracy of the photon therapy. We used an Electronic Portal Imaging Device (EPID) and Monte Carlo simulation (MC) for dose reconstruction. The therapeutic photons were irradiated to a phantom that simulated human body. The MC calculated all the photon process such as entering and being absorbed inside the phantom, and the formation of the EPID image. The reconstructed dose distributions were compared to the measurement. They agreed well with the measurements within 3%. The results suggested that our system reconstructed the dose distribution accurately. Those achievement were reported at The 107th Meeting of Japan Society of Medical Physics and The 7th Korea-Japan Joint Meeting on Medical Physics.
