1.“Model-based dose calculations for ocular brachytherapy”

Marielle Lesperance – Carleton University

Abstract: Ocular plaque brachytherapy has been shown to be as effective as complete removal of the eye for treatment of uveal melanoma. Despite this, local control is not always achieved and radiation damage to healthy eye structures may occur. In order to properly link treatment outcome with dose delivered, it is necessary to obtain accurate dose distributions. As current treatment planning assumes the patient is water-equivalent, eye geometry and composition are not taken into account. To assess dose sensitivity to these factors, we have created a full eye model with realistic dimensions and composition. This presentation will discuss the effects on dose of ocular media composition for three different radionuclide sources: I-125, Pd-103 and Cs-131. It will also include comparison between the current method of reporting dose to points of interest and dose to volumes of interest.

 2.“Optical imaging modalities for medical application - Optical Tomography”

Costel Flueraru – National Research Council Canada

Abstract: Medical imaging modalities play a significant role in improving the diagnosis, the clinical management of disease and the understanding of disease pathogenesis.  In the first part of this presentation I will review the optical imaging modalities and their relation with the conventional medical imaging techniques.  The second part will focus on new developments of optical coherence tomography and its applications in cardiovascular imaging and tissue characterization.
