Abstract

Aim

Exact knowledge of dosimetric parameters is an essential pre-requisite of an effective treatment in radiotherapy. In order to fulfill this consideration, different techniques have been used, one of which is Monte Carlo simulation.

Materials and methods

This study used the MCNP-4C[[ce:cross-ref refid="fn0005"]]b[[ce:footnote id="fn0005"]]bMonte Carlo N-Particle Transport Code – Version 4C. to simulate electron beams from Neptun 10 PC medical linear accelerator. Output factors for 6, 8 and 10[[ce:hsp sp="0.25"/]]MeV electrons applied to eleven different conventional fields were both measured and calculated.

Results

The measurements were carried out by a Wellhofler-Scanditronix dose scanning system. Our findings revealed that output factors acquired by MCNP-4C simulation and the corresponding values obtained by direct measurements are in a very good agreement.

Conclusion

In general, very good consistency of simulated and measured results is a good proof that the goal of this work has been accomplished.
