Monte 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 کاملMonte Carlo Calculations Supporting Patient Plan Verification in Proton Therapy
Patient's treatment plan verification covers substantial amount of the quality assurance (QA) resources; this is especially true for Intensity-Modulated Proton Therapy (IMPT). The use of Monte Carlo (MC) simulations in supporting QA has been widely discussed, and several methods have been proposed. In this paper, we studied an alternative approach from the one being currently applied clinically...
متن کاملMonte Carlo comparison of x-ray and proton CT for range calculations of proton therapy beams.
Proton computed tomography (CT) has been described as a solution for imaging the proton stopping power of patient tissues, therefore reducing the uncertainty of the conversion of x-ray CT images to relative stopping power (RSP) maps and its associated margins. This study aimed to investigate this assertion under the assumption of ideal detection systems. We have developed a Monte Carlo framewor...
متن کاملDosimetry of 188Re and 186Re sources based on Monte Carlo calculations for endovascular brachytherapy after balloon angioplasty
Background: Recent pre-clinical and clinical studies indicate that irradiation in the dose range of 15 to 30 Gy can reduce rate of restenosis in patients who have undergone an angioplasty. The use of filled balloon with radioactive solution was proposed as one of the possible intravascular irradiation techniques. Materials and Methods: The Monte Carlo N-particle Transport Code (MCNP4b) was used...
