Virtual Rescanning Mode (VRM)™
With one scan, Sonoscan’s Virtual Rescanning Mode collects comprehensive acoustic data at every X, Y, and Z coordinate. This detailed matrix of acoustic data is then digitally stored, allowing the operator to “virtually rescan” the component at any time, using the most common imaging modes and new techniques.
Components that are placed into high reliability situations (e.g., satellites, airplanes, missile systems) are often analyzed using this feature to provide a more complete archival documentation of the component for future evaluation.
The main capabilities of VRM include Time Domain Imaging (TDI), Frequency Domain Imaging (FDI), B-scan (cross-sectional) Imaging, ZipSlice/3V Imaging and Profile (depth of feature) Imaging. Each imaging mode provides unique information that combines to yield a more comprehensive analysis of a sample.
The following example illustrates the value of Sonoscan’s Virtual Rescanning Mode:
