It is widely accepted that there is substantial variability across institutions in the quality of radiotherapy treatment planning. Optimization in IMRT treatment planning can be a time consuming process as the planner attempts to satisfy competing objectives of maximizing therapeutic dose to the target volume while minimizing the dose to the adjacent organs at risk. It is also difficult to know a priori the extent of achievable tumor coverage and normal tissue sparing that can be achieved for a specific, individual patient. By using a database of prior optimized plans, our research group has shown that a knowledge-based treatment planning approach can aid to predict the achievable plan quality.


Dr. Vorakarn Chanyavanich recently received his PhD in medical physics from Duke University. He received his Master's degree from Stanford University. Currently, he is a medical physics resident in the Department of Radiation Oncology at Emory University. His research area of interest includes treatment planning, optimization, imaging informatics, and machine learning. Specifically, his current research project seeks to improve treatment planning quality and efficiency through the use of knowledge-based and expert-systems approaches.
