This thesis describes an image-based system for analyzing dose distributions produced during treatment planning of stereotactic radiosurgery. A review of stereotaxy and radiosurgery, particularly for the treatment of arteriovenous malformations (AVMs), is presented. The stereotactic apparatus and linear accelerator-based irradiation techniques used at McGill University are described in some detail. / The image-dose analysis software, running on a UNIX workstation, is presented, including software utilities for the evaluation of radiosurgery treatment plans based on magnetic resonance (MR) images. The importance of dose-volume histograms (DVHs) in the assessment of treatment plans is discussed, and the software developed to generate DVHs is described. / A technique for the experimental verification of calculated three-dimensional (3D) dose distributions is presented. This computerized approach is based on stereotactic principles and uses a plastic phantom and radiotherapy verification film as the dosimeter. The results indicate that, with some improvements, this is a viable technique for the experimental validation of stereotactic 3D treatment planning software.
