VisualSonics introduces new cardiovascular features in micro-ultrasound system

14 March 2006

Toronto, Canada. VisualSonics, developer of high-resolution, ultrasound-based micro-imaging systems, announced new cardiovascular functionalities for its Vevo 770 system making the platform more powerful and quantitative for cardiovascular researchers.

Providing significant improvements for the pre-clinical cardiovascular researcher, new features include Tissue Doppler Imaging (TDI), integrated blood pressure analysis, automated left ventricular functional analysis, anatomical M-Mode and extended measurement capabilities.

Dr. Attila Kovacs, Assistant Professor of Medicine, Washington University in St. Louis, a beta site tester, said: "The advanced cardiovascular functionality makes the Vevo even more useful in my pre-clinical cardiovascular research performed in the Mouse Cardiovascular Phenotyping Core Laboratory. By using the enhanced cardiovascular features, our team at Washington University was able to discover new data and insights related to our research activities."

"We are greatly encouraged by the research findings many of our customers have discovered by using the Vevo system," said VisualSonics President and CEO Tom Little. "We are happy that our decision to further the Vevo's unique offering in the pre-clinical micro-imaging and micro-ultrasound space is allowing customers to conduct and publish innovative work."

Cardiovascular studies using VisualSonics' Vevo technology by various researchers at leading academic institutions led to recently published findings in Circulation Research, The Journal of the American Society of Echocardiography, Circulation and The Journal of Ultrasound in Medicine and Biology.

The Vevo's new TDI feature allows quantitative myocardial analysis to be performed and used for regional myocardial strain rate. In addition, the new integrated blood pressure analysis functionality allows the Vevo 770 system to integrate a blood pressure signal from a third-party continuous pressure monitoring system. Examples of this include integration with conductance catheter and telemetry blood pressure monitoring. The integrated blood pressure can be combined with the Vevo ultrasound image data and corresponding measurements to perform pressure-volume and vascular strain analysis.

Other new features include the automated left ventricular (LV) functional analysis which provides semi-automated continuous tracing of the chamber walls in the left ventricle in either B- or M-Mode. In addition, the Vevo software automatically generates standard left ventricular measurements and calculations derived from the traced contours and collected physiological data. Finally, many enhancements have been added to the Vevo Measurement and Calculations package to ensure that it is complete, flexible, easy-to-use, and addresses the multiple needs of the small animal cardiovascular researcher.
