5-102  Image Optimization 
Effects  The bigger the level is, the higher the smooth effect achieves.   
 
Persistence 
Description 
This feature is used to superimpose and average adjacent elasto images, so as to 
optimize the image. 
Operations  Tap [Persistence] on the touch screen to adjust the parameter. 
The bigger the value is, the higher the frame optimization effect achieves.   
  The persistence function can remove image noise and optimize image effect to gain 
a more detailed image.   
 
Map Position 
Description  This feature is used to adjust the up/down position of the map.   
Tap [Map Position] on the touch screen to adjust the parameter.   
When the E Average function is enabled or disabled, the elasto curve is displayed 
based on different statistical amounts.   
 
Lesion 
Description  It is used to distinguish elastography data of the different lesion region.   
Operations  Rotate the knob under [Lesion] on the touch screen to adjust.   
 
Select/Bad 
Description  It is used to remove the desired frame from stress curve. The removed frame will not 
be calculated in STQ indices. 
Operations 
Rotate the knob under [Select/Bad] to select the desired frame, and press the knob 
to set the desired frame to “On”. 
5.15  Stress Echo 
Stress Echo is an option.   
 
CAUTION: 
Stress echo data are provided for reference only, not for confirming 
diagnoses. 
5.15.1  Overview 
The Stress Echo feature allows you to capture and review cardiac loops for multiple-phase (multiple-
stage) Stress Echo protocols. 
Stress Echo data consists of Stress Echo loops, wall motion scores, and all other information pertaining 
to the Stress Echo portion of a patient examination. 
A loop is a clip that displays the motion of an entire heart cycle, or from the beginning systole to the end 
systole, as indicated by the R-wave of the ECG trace and determined by the QT – Time Table.
