Integrating of Surgical and Radiation Therapy Technologies
Navigation, image-guidance and augmented visualization have become common tools in many surgical fields and interventional radiology. Simultaneously, radiation therapy today is critically dependent on image-guidance and computerized treatment planning.
Our group is developing methods of integrating several image guidance and navigation tools from both surgery and radiation therapy into a common treatment planning, delivery and monitoring platform. These include:
- Navigation and augmented visualization tools for brachytherapy
- Improved contouring methods for radiation therapy in luminal cancers by the registration of endoscopic imaging to CT and MR imaging
- Treatment planning that integrates both surgical and radiation modalities
- Treatment planning and real-time monitoring of locally ablative therapies such as photodynamic and photothermal therapies, including the use of enhanced nanotechnology agents
