Tissue Velocity Imaging (TVI) Checks
Introduction
TVI calculates and color codes the velocities in tissue. The
tissue velocity information is acquired by sampling of tissue
Doppler velocity values at discrete points. The information is
stored in a combined format with grey scale imaging during one
or several cardiac cycles with high temporal resolution.
Preparations
• Connect one of the probes, to the scanner’s left-most probe
connector.
• Turn ON the scanner.
The 2D Mode window is displayed (default mode).
• If needed, adjust the Display’s Brightness and Contrast
setting.
Press TVI.
Use the trackball (assigned function: Pos) to position the
ROI frame over the area to be examined.
Press Select. The instruction Size should be highlighted in
the trackball status bar.
NOTE: If the trackball control pointer is selected, press trackball to
be able to select between Position and Size controls.
Use the trackball to adjust the dimension of the ROI.
