VisualSonics Inc., from Toronto, O’Canada, is introducing a new in vivo high-resolution, ultrasound-based micro-imaging system called Vevo 770™. According to the company, the system is packed with features geared toward cardiovascular researchers.
From the press release:
According to Dr. Attila Kovacs, Assistant Professor of Medicine, Washington University in St. Louis, a beta site tester, “The advanced cardiovascular functionality makes the Vevo even more useful in my preclinical cardiovascular research performed in the Mouse Cardiovascular Phenotyping Core laboratory. By using the enhanced cardiovascular features, such as TDI, our team at Washington University was able to reliably measure intramyocardial velocity gradients and strain rates in different mouse models of cardiac diseases. Our preliminary experience with the integrated telemetry blood pressure monitoring system also shows that this new feature will be highly valuable in monitoring load-independent parameters of cardiac performance on a longitudinal basis…”
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, including the automated left ventricular (LV) functional analysis 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 the 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 address the multiple and different needs of the small animal cardiovascular researcher.
