Analysis of Relative Biological Effectiveness of Proton Beams and Iso-effective Dose Profiles Using Geant4
Background: The assessment of RBE quantity in the treatment of cancer tumors with proton beams in treatment planning systems (TPS) is of high significance. Given the significance of the issue and the studies conducted in the literature, this quantity is fixed and is taken as equal to 1.1.Objective: The main objective of this study was to assess RBE quantity of proton beams and their variations ...

متن کاملInvestigation of tumor motion influence on applied dose distribution in conventional proton therapy vs. IMPT a 4D Monte Carlo simulation study
Background: in radiation treatment of moving targets located in thorax region of patient body, the delivered dose does not match with the planned treatment, resulting in some over and under dosage in the tumor volume, as a function of motion magnitude and frequency. Several efforts have been done to investigate the target motion effects on dose distribution in the target and surrounding normal ...
متن کاملEvaluation of variable relative biological effectiveness and the creation of homogenous biological dose in the tumor region in helium ion radiation to the V79 cell line
In radiation therapy, ions heavier than proton have more biological advantages than a proton beam. Recently, ion helium has been considered due to high linear energy transfer (LET) to the medium and a higher relative biological effect (RBE). To design the spread-out Bragg peak (SOBP) of biological dose for radiation with any type of ion, we need exact values of RBE, which is dependent to dose, ...
