Our state-of-the art ultrasonic measurement system has a wide range of applications in cardiovascular research and many related disciplines. Whether the piezo-electric transducers are placed on the heart, other organs, or synthetic materials, the principles behind Digital Sonomicrometry are the same. Any task that involves making dimensional measurements in liquids or soft solids is a perfect task for the Sonometrics Digital Sonomicrometer and Data Acquisition System. Highly accurate measurements of strain, length, area, thickness, volume, and geometry can be made in natural and man-made materials in vivo or in vitro. The following are only a few sample applications:

Cardiac measurements:
