Virtual Touch Imaging Measurements

Virtual Touch imaging supports basic measurements, including area ratio and distance ratio.
You can perform all basic measurements (such as distance, ellipse, and trace) on either dual
image.
When the shadow function is active, the system displays the measurements on both the
measured image and the shadow image.
To
Activate the shadow function
during measurements in a
dual-screen format
Exit the shadow function

Do This
1. Activate the positioning or sizing function:
● Press SELECT.
○ For systems without a touch screen, press NEXT.
2. Roll the trackball to reposition or resize the ROI.
The software restricts the depth of the ROI.
Note: You cannot adjust the ROI during acquisition.
 Press UPDATE.
An audible tone indicates when volume acquisition begins and when acquisition is
complete.
When acquisition is complete, the system automatically freezes. During system
freeze, a cooling timer indicates the remaining time (in seconds) until the
transducer is available for image acquisition.
– In dual display format, the system displays relative tissue stiffness within the
ROI on the right image.
– In full-screen display format, the system displays the relative tissue stiffness as
a transparent color overlay on the 2D image.
The system also activates CINE. The last frames of CINE include the Virtual Touch
imaging acquisition.
1. Unfreeze the image.
2. Adjust the ROI size and position, if necessary.
3. Press UPDATE to begin acquisition.
1. Activate a dual format.
● Select Dual.
○ For systems without a touch screen, double-click UPDATE.
2. Press UPDATE.
 Rotate [VTI Map].
 Press 2D.
Do This
1. Select Shadow.
2. Perform a measurement, such as distance, trace, or ellipse, on either image.
When the measurement is completed, the measured image displays the
measurement markers and the dotted measurement line; the shadow image
displays only the dotted measurement line.
 Select Shadow again.
