Evaluation of an electron Monte Carlo dose calculation algorithm for electron beams

The electron Monte Carlo (eMC) dose calculation algorithm of the Eclipse treatment planning system is based heavily upon Monte Carlo simulation of the linac head and modeling of the linac beam characteristics with minimal measurement of beam data. Commissioning of the eMC algorithm on multiple identical linacs provided a unique opportunity to systematically evaluate the algorithm with actual me...

Evaluation of an electron Monte Carlo dose calculation algorithm for treatment planning

The purpose of this study is to evaluate the accuracy of the electron Monte Carlo (eMC) dose calculation algorithm included in a commercial treatment planning system and compare its performance against an electron pencil beam algorithm. Several tests were performed to explore the system's behavior in simple geometries and in configurations encountered in clinical practice. The first series of t...

Evaluation of Electron Contamination in Cancer Treatment with Megavoltage Photon Beams: Monte Carlo Study

Background: Megavoltage beams used in radiotherapy are contaminated with secondary electrons. Different parts of linac head and air above patient act as a source of this contamination. This contamination can increase damage to skin and subcutaneous tissue during radiotherapy. Monte Carlo simulation is an accurate method for dose calculation in medical dosimetry and has an important role in opt...

Multi-leaf Collimation of Electron Beams with Monte Carlo Modelling and Dose Calculation

Tumours and other superficial targets are often treated with electron beams in radiotherapy. The build-up dose and the therapeutic range of electrons are controlled by selecting the electron energy and by using a water-equivalent bolus placed on the skin. Currently, the shaping of clinical electron beams is often done via low melting point alloy block inserts individually made for each patient....
