10  Virtual Touch  Applications 
10 - 6  Instructions for Use 
Virtual Touch Quantification 
Use Virtual Touch quantification to measure tissue for a selected region of interest as shear 
velocity (Vs) or elasticity (E).  
Note: Because shear waves do not propagate through fluid, do not use Virtual Touch quantification 
to measure fluids. 
Virtual Touch quantification supports the following transducers and exam types: 
  4C1 (abdominal exam) 
  4V1 (abdominal exam) 
  9L4 (breast or thyroid exam) 
  6C1 HD (abdominal exam) 
Use the system configuration menu to display shear wave measurements as velocity (m/s) or 
elasticity (kPa) units in the image screen and patient report.

To activate Virtual Touch quantification: 
  During 2D-mode or 2D-mode with THI active, select the control assigned to activating the 
feature:  
●  Press E and then select Virtual Touch Quantification, if necessary. 
○  For systems without a touch screen, select Virtual Touch Quantification.
