Consider potential of gold nanoparticles with proton therapy compared with KV and MEV X-ray therapy.
Introduction: Many study shown the effectiveness dose enhancement with gold nanoparticles (GNPs), especially with low-energy x-rays. Recently, proton beam radiation therapy (PBRT) has attention as a treatment for tumors. The advantage in PBRT, which releases high dose at the controllable Bragg peak position that localized for Au target and the released dose increased in depth....
متن کاملCalculation of Neutron Dose Ratio of Heart, Lung and Liver due to breast cancer Proton Therapy using MCNPX code
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...
متن کاملQuantum mechanical proton range in human body
Introduction: Proton therapy delivers radiation to tumor tissue in a much more confined way than conventional photon therapy thus allowing the radiation oncologist to use a greater dose while still minimizing side. Materials and Methods: protons release most of their energy within the tumor region. As a result, the treating physician can potentially give an...
متن کاملEvaluation of the effective dose during PBFT for brain cancer: A Monte Carlo Study
Introduction: Recently, an approach exploiting the proton therapy biological enhancement by using Boron atoms injected inside a tumor, has been proposed. Three alpha particles with an average energy around 4MeV are emitted from the point of reaction between a proton and boron. In addition, the 719 keV prompt gamma emitted by the proton Boron fusion reactions can be used for on-...
متن کاملTreatment of Helicobacter Pylori in Children
Childrenwith Helicobacter infection need treatment. The aim of treatment is elimination of H.Pylori. Most patients with this infection are asymptomatic and without peptic disease. Treatment and management of these patients are controversy. Conventional Treatment: The best treatment for H. pylori eradication regimens should have cure rates of at least 80%, be without major side effects, and indu...
