Analysis
Analysis consists of viewing previously saved loops and 
assigning scores to each cardiac segment, in order to quantify 
the function of the muscle, or wall motion.
Depending on the protocol configuration, the analysis stage 
can be started automatically after completion of the stress test 
or it can be started manually. In this case, the usual procedure 
consists of sequentially opening all image groups (if defined) 
and perform scoring...
