The Sonometrics digital sonomicrometer is a device that can accurately measure dynamic and static dimensions in ultrasound-compatible fluids and materials such as biological soft tissue (muscle, fat, soft-tissue organs, etc) and synthetic materials (ie rubber, gel, plastic, etc). These measurements are made using small piezoelectric sensors (commonly referred to as "crystals") that are placed in or attached to the material or object of interest.

We have two basic hardware platforms. One is known as the Ultrasound Dimension Gauge (UDG) and performs 2 dimensional measurements between 2 pairs of piezo crystals. The measurements are output from the UDG as analog signals (0 - 5 volts) that are acquired by other data acquisition systems. The second system is known as the DS-3 and is a data acquisition unit that processes signals from 8 to 32 crystals simultaneously and interfaces via USB with any computer or laptop running Windows XP or higher. This unit can also acquires analog signals from other devices or sensors(ie pressure, flow, EMG/ECG, force, etc) and combines all signals during acquisition into the same data file for post- acquisition analysis. DS-3 systems measure every dimension between every crystal, which allows for the spatial 3D-XYZ relations between crystals to be determined. All signals are displayed in real time on our Sonolab data acquisition software and several different post-acquisition programs are available for physiology-focused data analysis in areas such as cardiac, gastro-intestinal and biomechanics.
