Abstract
Electron beams that possess the physical property of rapid dose falloff are useful for the treatment of superficial tumors as they spare organs at risk behind the target. One of the issues that arise in the safe delivery of electron beam therapy involves the accuracy of the dose calculation algorithms. Recent advances in Monte Carlo (MC) techniques now allow accurate and fast (∼minutes) calculations that are reasonably acceptable for clinical use. In this study, we evaluated a commercial MC electron beam dose calculation algorithm under clinically practical use conditions and compared this to a conventional pencil beam (PB) calculation for cases of clinical examples and phantom measurements.
