Robotics & Image Guidance for Brachytherapy
One of the key advantages of brachytherapy is the application of dose from within the tumor. Hence, surrounding organs can be spared effectively, e.g., by placing small radioactive seeds in a needle in HDR brachytherapy. However, as the dose gradient around the seed is steep, it is important to place needles precisely. We study the use of robotics in combination with sensors and advanced imaging to analyze the needle position with respect to the tissue.
