Research areas
- The use of electronic portal imaging devices for the dosimetric verification of complex radiotherapy treatments: This project aims to increase the understanding of the fundamental dosimetric response of electronic portal imaging devices (EPID’s) to a megavoltage radiotherapy beam; and to develop new methods for predicting the dose deposition in the EPID using a combination of Monte-Carlo calculation methods and analytical dose calculation algorithms.
- The development of Monte-Carlo techniques for verification of radiotherapy treatments: An investigation of the accuracy of radiotherapy dose calculations produced by Treatment Planning Systems, by comparison with Monte-Carlo simulation results. Differences between the treatment planning system and Monte-Carlo dose distributions will be assessed in terms of their radiobiological significance on the patient’s treatment outcome.
- Monte-Carlo modelling of kilo-voltage x-ray units for radiotherapy applications: This project is developing Monte-Carlo models of the kV x-ray tube and a-Si flat panel imager of a radiotherapy cone beam CT system. The aim is to investigate whether the x-ray tube and detector can be optimised to improve the image quality.
