Abstract

We have recently developed a novel contrast-based ultrasonic particle imaging technique (Echo PIV) for multi-dimensional blood flow imaging. In the technique, the quality of vectors is important for quantitative blood flow imaging. Here we introduce an algorithm for vectors correction by filtering in frequency domain and applying continuity equation. The algorithm was tested in the Echo PIV imaging of rotational flow field and found to be effective in improving the quantitative blood flow imaging quality.
