Optimizing RTMC
RTMC is by default scanning in low power mode to avoid 
destruction of slow moving contrast in the myocardium. This 
setting is required for real time contrast imaging, but is sub-
optimal for tissue imaging.
•  To obtain good baseline images, the power may be 
increased prior to contrast injection, but must be reset to its 
default value before contrast injection or infusion to avoid 
destruction of the contrast agent.
•  If...

Introduction
The Vivid 7/Vivid 7 PRO Ultrasound unit provides functionality 
for two measurement conventions:
A study is a set of 
related measure-
ments, or measure-
ments that are 
logically grouped 
together. The mea-
surements in a 
study are some-
times used in a for-
mula to calculate 
new parameters 
(e.g. biplane volume 
with EF, SV and 
CO).• Assign and Measure (Measure Protocols): the user 
selects a study consisting...
