Ziosoft Inc., of Redwood City, Calif., has announced that it has received U.S. Food and Drug Administration clearance for its CT brain perfusion application. 

Using standard commercial hardware, the software can provide brain perfusion functionality to clinicians as a thin-client application. According to the company, the technology assists radiologists in stroke assessment by providing a color map of cerebral blood flow and other perfusion-related parameters from CT images of the brain.

The application includes both image manipulation tools and measurement tools, such as cerebral blood volume, blood flow and mean transit time.
