Experimental validation of the filtering approach for dose monitoring in proton therapy at low energy.
The higher physical selectivity of proton therapy demands higher accuracy in monitoring of the delivered dose, especially when the target volume is located next to critical organs and a fractionated therapy is applied. A method to verify a treatment plan and to ensure the high quality of the hadrontherapy is to use Positron Emission Tomography (PET), which takes advantage of the nuclear reactio...
متن کاملA method for range calculation of proton in liquid water: Validation study using Monte Carlo method and NIST data
Introduction: The main advantage of using ion beams over photons in radiotherapy is due to their inverse depth-dose profiles, allowing higher doses to tumors, while better sparing normal tissues. When calculating dose distributions with ion beams, one crucial point is the uncertainty of the Bragg-peak range. Recently great effort is devoted to enhance the accuracy of the comput...
متن کاملSimulation of beam record data for 4D dose calculation
Treatment of moving targets can result in local over and under dosage due to interference effects of the beam application and the motion of the target. First experimental studies [1] as well as theoretical works [2, 3] showed that multiple irradiations with an accordingly reduced dose per irradiation reduce these inhomogeneities due to averaging effects. If the multiple irradiations are perform...

Introduction: The proton beam produced in particle accelerators has an appropriate therapeutic potential. In this research, proton therapy of breast cancer is simulated using the MCNPX code in a MIRD phantom, also the contribution of scattered neutron dose during the proton therapy were calculated for the Heart, Lung and Liver. Materials and Methods: For si...
متن کاملMonte Carlo calculations of dose distribution for the treatment of gastric cancer with proton therapy
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...
