Doppler and Color Flow Operation Keys
Use these controls and keys to operate the Doppler and Color
Flow functions.
D
A dual-function control that activates one function when the control is
pressed and another function when the control is rotated.
Pressing the D control displays a Doppler cursor and Doppler gate for
placement in the 2D-mode image. Depending on the system presets,
pressing the
D control the first time can also initiate display of the
Doppler spectrum.
For pulsed Doppler, pressing the D control a second time causes the system
to display 2D-mode with Doppler and to transmit an audible Doppler signal.
Doppler Search mode
enables transmission of an audible Doppler signal
the first time you press the D control. Pressing the D control a second time
changes the display to 2D-mode with Doppler. Use the system presets to
activate Doppler Search mode.
Rotating the D control clockwise increases the gain; counterclockwise
rotation decreases the gain. The range for gain settings is from 30 dB
to 60 dB.
The gain value for the Doppler image displays as the last number in the
Image Parameter area, at the bottom of the screen.
D: 100/ 4.8/ 45
Doppler gain (dB) is indicated by the shaded value.
Triplex
Allows mixed-mode imaging to display simultaneously, in real-time.
An example of mixed mode imaging is 2D-mode with color and Doppler.
