Assessing blood flow in isolated pig heart with USCA

In order to study heart perfusion by UltraSound Contrast Agents (USCA) means, and mainly the relationship between flow rate and acoustic signal variation versus time, an experimental setup has been developed. Signal versus time variation curves are deduced from local analysis of RF data. The setup has been validated by comparison between measured dilution curves and theoretical results. Finally, results are shown for heart based manipulations.
