FLASH Correlation: A New Method for 3-D Ultrasound Tissue Motion Tracking and Blood Velocity Estimation

Ahmed A. Morsy and Olaf T. von Ramm

ABSTRACT We report a new method for tracking tissue motion and blood flow in three dimensions (3-D) using successive volumetric ultrasound scans. The method is based on combining the concepts of feature tracking and 3-D correlation search to achieve a compromise between accuracy and computational efficiency. This paper introduces the new method and the experimental setup used for its evaluation in a tissue-mimicking material. Results are presented demonstrating that the new method has both satisfactory tracking performance and the potential for practical real-time implementation.
