Abstract:
Monte Carlo techniques have been shown to be the most accurate method of
modelling radiation transport and dose deposition. With increasingly complex
radiotherapy techniques being employed in the continuing fight against cancer,
Monte Carlo techniques provide a de finitive method to assess the accuracy of
these techniques and the accuracy of the procedures used to test them. This
thesis established a method to tune a linear accelerator model, in an efficient
process. This model was then employed to examine two techniques used currently
in the measurement of the absolute dose for the quality assurance of individual
patient IMRT plans.
