A Block Matching Based Approach with Multiple Simultaneous Templates for the Real-Time 2D Ultrasound Tracking of Liver Vessels

摘要

PurposeThe implementation of motion management techniques in radiation therapy can aid in mitigating uncertainties and reducing margins. For motion management to be effective, it is necessary to track key structures both accurately and at a real-time speed. Therefore, the focus of this work was to develop a 2D algorithm for the real-time tracking of ultrasound features to aid in radiation therapy motion management.
