Background: In radiation therapy with ion beams, lateral distributions of absorbed dose in the tissue are important. Heavy ion therapy, such as carbon-ion therapy, is a novel technique of high-precision external radiotherapy which has advantages over proton therapy in terms of dose locality and biological effectiveness.Methods: In this study, we used Monte Carlo method-based Geant4 toolkit to s...
Proton therapy is a common form of external radiation therapy based on the manipulation of Bragg peak of this beam, it can treat the tumor by delivering high levels of doses to it, while protecting surrounding healthy tissues against radiation. In this work, the dose distribution of proton and secondary particles such as neutrons, photons, electrons and positrons in gastric cancer proton therap...
One major strategy, technology-driven improvement of treatment conformity in cancer treatment, including advanced image guidance, advanced charged particle therapy (CPT), and application of nanoparticles in hyperthermia, will enable further widening of the therapeutic window of cancer treatment in the era of precision medicine. The state of the art treatment in photon-therapy is advanced 3D...
