Characterize and measure physiology by using the PW Doppler Mode to visually and audibly analyze the velocity of flow in vessels. The Doppler Sample Volume, a region of interest, is guided with the Vevo 770's high-resolution imaging.









The sample volume size may be set at levels sensitive enough to discriminate flow from individual arterioles and venules or measure flows in larger vessels. Record visualizations and audio output in standard PC or Macintosh-compatible formats to playback in multimedia presentations.
