Sonometrics Corporation is dedicated to the advancement of medical and biological research by applying innovative products to challenging questions. We strive to provide state-of-the-art instrumentation and software as well as leading-edge customer service to scientists around the world. Incorporated privately in 1993, Sonometrics was based on instrumentation developed in the course of cardiac research being carried out at Robarts Research Institute in London, Ontario Canada. Using pulsed ultrasound techniques, our distance measurement products have resulted in productivity increases in many labs where previous methods were inaccurate, irreproducible, costly and labor-intensive. Product Overview Sonometrics manufactures sonomicrometer hardware and software for use in various scientific applications. Physiological parameters such as cardiac segment lengths, chamber dimensions, ventricular volumes, wall thickness and wall motion is measured by our transducers and instrumentation and recorded and analyzed by our software. The essence of our measurement technology is small piezo-electric transducers "crystals" which are implanted or attached to soft tissue structures (cardiac muscle, skeletal muscle, arteries, veins, heart valves, etc.) and the distances between the transducers are continuously measured. For muscle and cardiac applications, items such as fractional shortening, wall thickening (thickening fraction), and ventricular volumes are calculated directly from the distance measurements. Our data analysis software takes those parameters one step further and computes stroke work, stroke volume, ejection fraction, ESPVR (aka E-Max or compliance), EDPVR, and PRSW. The benefits of using our products to make these measurements vs other methods (such as echocardiography, MRI, or conductance catheter) are significant and too numerous to mention on this page. Our products have a proven record in the scientific world and can be thought of as providing a benchmark by which many other measuring and imaging modalities are judged. Our measurement systems are regularly used to assess the efficacy and performance of new medical devices and drugs by academic research labs and both small and large biomedical device companies. Some examples include assessing the improvement in cardiac function in conjunction with LVAD's, artificial valves, revascularization devices and pharmaceutical agents, genetic manipulation, myocardial transplantation, and new surgical techniques or surgical-aid devices.
