P6 - Robotic ultrasound for SBRT of the prostate

During stereotactic body radiation therapy (SBRT), respiratory motion can be effectively compensated, e.g., using the robotic CyberKnife. However, prostate motion is mostly spontaneous, and frequent X-ray imaging adds to the overall dose. To overcome these limitations and to allow for continuous motion tracking we are working on robotic ultrasound image guidance. We study machine learning approaches and volumetric ultrasound for estimating tissue motion. Moreover, we work on integrating the ultrasound robot into the overall treatment scenario.
