10 Virtual Touch Applications
10 - 18 Instructions for Use
To activate Virtual Touch IQ:
1. During 2D-mode imaging, select the control assigned to activating the feature:
● Press E and then select Virtual Touch IQ.
○ For systems without a touch screen, select Virtual Touch IQ.
Virtual Touch IQ button.
The system activates a full-screen format and displays a region of interest (ROI).
2. To activate a dual display format:
● Select Dual.
○ For systems without a touch screen, double-click UPDATE.
The left image displays the ROI. The right image is blank.
To
Do This
Adjust the size or position of
the region of interest (ROI)
prior to acquisition
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.
Begin acquisition
Note: You cannot adjust the ROI during acquisition.
 Press UPDATE.
The system acquires a single image frame and then freezes the image and applies
the velocity image display setting. During system freeze, a timer indicates the
remaining time (in seconds) until the transducer is available for image acquisition.
Change the image display
setting
 Rotate [Shear Wave] to select the required setting:
– Velocity depicts the range of shear wave velocity or elasticity values from
minimum to maximum. Shear wave velocity is slower in soft tissue and faster in
stiff tissue. Elasticity is higher in soft tissue and lower in stiff tissue. The color
bar displays the minimum and maximum range of the shear wave velocity and
elasticity measurement.
– Quality depicts the combination of shear wave displacement magnitude and the
signal-to-noise level from low (LO) to high (HI). A low displacement magnitude
and high noise level are depicted as low quality. A high displacement magnitude
and low noise level are depicted as high quality.
– Time indicates the travel time of the shear wave from slow (S) to fast (F).
– Displacement indicates the magnitude of the shear wave displacement of
tissue from low (LO) to high (HI). Displacement is higher in soft tissue and lower
in stiff tissue.
Reactivate Virtual Touch IQ
acquisition after the
automatic freeze period
ends
1. Unfreeze the image.
2. Adjust the ROI size and position, if necessary.
3. Press UPDATE to begin acquisition.
