10.1.1 B/CFM/DPI/TDI Operation in Spectral Doppler Mode
When the PW/CW spectral display is inactive, B/CFM/DPI/TDI operations in the PW/CW
duplex mode are possible.
For B mode operation, refer to Chapter 5.
For CFM operation, refer to Chapter ?? .
For DPI operation, refer to Chapter 7.
For TDI operation, refer to Chapter 8.
The following two items shown in the menus in Figure 10.3 are specific to the spectral
Doppler duplex mode. Refer to Section 10.1.2 and Section 10.1.3 for explanations.
For PW operation, see Section 10.2 .
For CW operation, see Section 10.3 .
10.1.2 2D Refresh
2D REFRESH
➣
Note that this function only has effect for PW-duplex mode.
Set this item to On to enable the real-time 2D image display when spectral display is active.
When 2D Refresh is set to Off, the 2D image is frozen once the spectral display is active.
Usage instructions:
• Press
to select 2D REFRESH .
• Turn the function knob to turn on or off the
2D REFRESH function.
10.1.3 Display Format
DISPLAY FORMAT
Each PW-duplex or CW-duplex mode has six possible display formats. The screen layout in
spectral Doppler duplex mode is similar to that in M-duplex mode. Refer to illustrations in
Figure 9.3 , page 9-5.
10.2 PW Mode Operation
10.2.1 Sample Volume Gate Adjustment
Adjustment of the sample volume gate is possible during the real time PW mode scan.
Follow instructions below to adjust the sample volume gate.
• Move the trackball to change the location of the gate; the spectral Doppler cursor
will be moved together. For phased array probes, the angle of the spectral Doppler
cursor is changed; for linear array probes, the spectral Doppler cursor moves hori-
zontally.
