Using Tissue Doppler Imaging

The following section describes Tissue Doppler controls and how to use them.

Note the following Doppler mode guidelines:

•Touching PW or CW turns on Spectral, unless depth marks are used.

•In PW nonspectral mode, pressing the key automatically turns on

Spectral.

• Spectral is available in 2D/BMode, Color, and Angio when depth marks

are used.

•In Spectral, pressing turns on BMode Live (2D-Live if in Cardiac).

• When PW is turned on, the gate automatically moves away from the edge of

the image.

•Touching Cursor Angle when highlighted sets the angle to zero, except

when Intelligent Doppler is active or the image is frozen.

•In PW Spectral, you can display Heart Rate from a Doppler trace and

make a measurement.

For more information on PW and CW modes, see “PW and CW Imaging” on

page 7-79.

Depending on the imaging mode being used, the Tissue Doppler controls

include

•Color Gain

• Smoothing

•Color Map

• B/W Suppress

• PW Scale

• Reject

•Colorize

•Gate Length

•Compress

•Power
