Choosing a Color Map
The Color Map menu chooses which of five color maps is used to show Color Doppler
data. You can configure the color map independently for each exam by selecting an exam,
then a color map. You do not need to click
Save
or
Apply
to set the color map. When you
select a different exam, the Terason software loads the color map for the selected exam.
The color maps are designated A through F in the menu. Some maps use more colors than
others, and some display in a smoother gradient than others.

Special Cardiac Image Controls
Two controls on the CD Image Control window are only active when using the 4V2A
transducer with the Cardiac exam presets.
2D Suppress
Selecting 2D Suppress narrows the width of the displayed image to the region of interest.
This increases the Color Doppler frame rate.
To apply 2D Suppress, click the 2D Suppress button on the CD Image Control window.

Tissue Doppler Imaging
Selecting tissue Doppler imaging (TDI) optimizes the image controls for imaging tissue
motion. The control settings vary with the selected scan mode. The control values can be
adjusted and preset independently of non-TDI settings. TDI is disabled when the image is
frozen.
To apply tissue Doppler imaging, click the TDI button on the CD Image Control Window.

Using the Console
When the console is extended while live imaging in Color mode, the Scan Mode toolbar
changes to display the current settings of a group of controls. The specific control settings
displayed vary, depending on which transducer is connected and on other selections.
Pressing the left and right arrow buttons at the left-center of the console changes the
controls displayed in the four boxes.
