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.
Preparation
1. Connect one of the probes.
For available probes, See ‘Available probes’ on page 3-30
for more information. .
See ‘Connect a probe’ on page 3-17 for more information.
about connecting the probes.
2. Turn ON the scanner (if it isn’t turned on already).
