Toronto, Ontario-based VisualSonics, a developer of high-resolution, ultrasound-based, in vivo micro-imaging systems, announced that it has sold its 200th VevoT platform.  The company feels that its success is indicative of the significant demand for micro-ultrasound technology within biotechnology, pharmaceutical and medical research organizations. Another sign? The company said that it saw quarterly revenues of a few hundred thousand dollars in 2003. Now VisualSonics is experiencing a 145 percent compounded annual growth rate, quickly reaching its current $24 million in annualized sales, according to a release.
