چکیده

Experiences with the parallelization of the Phase Space Evolution (PSE) model for electron beam dose calculation are discussed. It is shown that the communication cost in a parallel implementation of the PSE model can be kept small. However, because of the dynamical behaviour of the work load during a PSE simulation special measures must be taken to obtain a good load balance among the processors. The results show that a parallel version of the PSE model with a linear speedup of about 0.5 times the number of processors is feasible.

Monte Carlo Simulation of a Linear Accelerator and Electron Beam Parameters Used in Radiotherapy

Introduction: In recent decades, several Monte Carlo codes have been introduced for research and medical applications. These methods provide both accurate and detailed calculation of particle transport from linear accelerators. The main drawback of Monte Carlo techniques is the extremely long computing time that is required in order to obtain a dose distribution with good statistical accuracy. ...

Assessment of an Unshielded Electron Field Diode Dosimeter for Beam Scanning in Small- to Medium-Sized 6 MV Photon Fields

Introduction Radiotherapy planning systems require many percentage depth dose (PDD) and profile measurements and there are various dosimeters that can be used to obtain these scans. As dose perturbation is particularly troublesome in smaller photon fields, using a low-perturbation, unshielded electron field diode (EFD) in these fields is of interest. The aim of this work was to investigate the ...
