A freehand sweep was performed across the anastomotic site, and multiple images were stored to disk, at 17 Hz. These were then segmented to show only color information (vascular flow) using purpose\u2010designed software (CQ analysis) and the files reconstructed into a three\u2010dimensional volume, for multidirectional viewing and movie generation.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Both arterioarterial and arteriovenous anastomoses could be visualized in detail.
