Move the color bars onscreen Up and Down the screen to prevent interference with
imaging data.

M-STB Sensitivity
0-4
Allows user to adjust the degree of sensitivity used when displaying M-STB Index.
Higher values are more sensitive to motion and will result in more frequent changes to
onscreen graphic.

selecting data to display etc)
Map Toggle to alternate 2D SWI color maps.
Map 0 indicates no color overlay. 2D SWI data is displayed in grayscale.
Map 2 and 3 are color maps
Scale Change the maximum m/s or kPa displayed on the 2D SWI color bar.

Tissue Tracking Quantitative Analysis (TTQA)
CAUTION:
It is provided for reference, not for confirming a diagnosis.
Tissue Tracking Quantification Analysis (TTQA) is a separately purchased option
which provides a tissue tracking function for myocardial movement evaluation.
The ultrasound system scans each pixel position frame by frame within the cardiac cycle, and then
uses a regional matching method and auto-correlation searching method to trace each spot and
calculate the movement, to determine myocardial motion in a more quantitative method.
TTQA must be assigned to a programmable function key before use. These keys can be configured
in Setup/Keys.
4. Press Setup / Keys.
5. Click to select TTQA to the desired key.
6. Click Save to complete the setting.
Once configured, TTQA is invoked by pressing the configured function key.
• Basic Procedures for TTQA
1. Select and open a Cardiac Clip from Review or Archive, with ECG containing at least 2
cardiac cycles (preferably 6 cardiac cycles)
2. Press the configured key (such as F2) to enter the TTQA feature.
a. System enters the TTQA function with 1 heartbeat playing on the upper screen and
TTQA strip on lower screen
3. Select which view is to be evaluated using the View Type OLED
4. Select desired Tracking Cycles (1 or 3) using the OLED
5. Select which heart beat range will be evaluated using the Cycle OLED
