An audible tone indicates when volume acquisition begins and when acquisition is

When acquisition is complete, the system automatically freezes and displays the
tissue shear velocity (Vs) or elasticity (E) and ROI depth in the measured results.
During system freeze, a cooling timer indicates the remaining time (in seconds)
until the transducer is available for image acquisition.
Note: If the system displays the measurement values as x.xx, the confidence
interval threshold for measurement quality was not reached. Repeat the acquisition
until the system displays a numerical value instead of x.xx.
The system also activates CINE. The last frames of CINE include the Virtual Touch
quantification acquisition.
