Figure Lengend Snippet: Speed maps measured by the four-tap CMOS image sensor for (a) ground glass and (b) Intralipose at different flow speeds. The estimated speed was calibrated. (c) An example of a captured raw image for the Intralipose. The flow speed maps were obtained from a single frame. No averaging was performed.
