Running LV Contrast
The LV Contrast application works with the 3S-RS, and 6T-RS
probes.
1. Press

on the control panel.
A list of the connected probes is displayed.
The
Application menu for the selected probe is listed.
2. Trackball to LV Contrast application.
3. Press
SET
to launch the application.
4. Perform the acquisition.
Optimizing LV Contrast
The default setting for the LV contrast application is optimal
setting for the application (On 3S probe: MI=0.5; Freq.=1.7/3.4;
Focus=9 cm). However, depending on the acoustic window of
the patient or the specific contrast agent being used, there may
be a need for further adjustment.
If image quality is not acceptable before contrast injection, the
power level should be increased. When contrast is observed in
the left ventricle, the power should be reduced to a level giving
homogenous opacification with no destruction (shown as a
swirling pattern) of the contrast agent in the LV cavity. If a
swirling pattern is observed and persists after the LV cavity has
been filled with contrast, the power should be reduced until
homogenous opacification is obtained.
WARNING
Always read and follow carefully the manufacturer instructions
on the contrast agent label.
CAUTION
Too high Power setting will destroy the contrast agent in the LV
cavity.
