Fast range-corrected proton dose approximation method using prior dose distribution

Proton dose distribution measurements using a MOSFET detector with a simple dose‐weighted correction method for LET effects

We experimentally evaluated the proton beam dose reproducibility, sensitivity, angular dependence and depth-dose relationships for a new Metal Oxide Semiconductor Field Effect Transistor (MOSFET) detector. The detector was fabricated with a thinner oxide layer and was operated at high-bias voltages. In order to accurately measure dose distributions, we developed a practical method for correctin...

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...

Dose for Proton Irradiation

With the increase in the amount of time spent EVA that is necessary to complete the construction and subsequent maintenance of ISS, it will become increasingly important for ground support personnel to accurately characterize the radiation exposures incurred by EVA crewmembers. Since exposure measurements cannot be taken within the organs of interest, it is necessary to estimate these exposures...

Fast Neutron Absorbed Dose Distribution Characteristics in the Energy Range 10–80 MeV

Dose distribution of protons and flux of secondary particles in breast proton therapy.

Introduction: Proton therapy is newer therapeutic method for early stage breast cancer. Proton beams release most of their energy in the Bragg peak and then will be a rapid decline in their end. When protons interact with matter, produce secondary particles like neutrons and gammas, and these unwanted radiation has no beneficial effect and also is believed to increase the risk ...
