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.
