Research Highlights

Stronach Regional Cancer Centre is actively engaged in research activities in Radiation Medicine. Besides participation in clinical trials, we are also active in developing new clinical techniques for radiation treatment, for example, active breath control for all left breast treatment, VMAT treatment for esophagus site and 4D CBCT for SBRT lung. We reported findings in the form publication in peer review journals or presentation in international meetings. We are also interested in developing new QA techniques and processes. We recently developed a technique for QA of jaw matching with the MapCheck device and published the result in Medical Physics. In addition, education research includes development of IGRT refresher module which can be used in radiation programs for continuing education.
