Color Doppler Mode Checks
NOTE:
Different menus are displayed depending on which Color Doppler Mode (CFM, PD or TD) is selected.

Color Doppler Mode (CFM, PD, TD) Functions
Step
Task
Expected Results
1
Color Box Position and
Color Box Size
Adjust the Box- Position resp. Size with the
TRACKBALL
in the 2DSingle image.
The
upper trackball key
changes from Box position to Box size.
2
CFM Gain
PD Gain
TD Gain
Rotate the
C MODE
key to ensure that continuous flow is displayed, where appropriate.
Rotate the
PD MODE
key to adjust the Power Doppler Gain.
Rotate the
C MODE
key to adjust the Tissue Doppler Gain.
3
2D+2D/C (PD or TD)
Changes the Single image display to two simultaneous half images. The left frame shows only
the 2D Mode image. The right frame shows the 2D Mode image with color information.
4
Steering
Beam Steering is only possible with linear probes in CFM and PD Mode.
5
Invert
The color of the color wedge inverts around the baseline. (impossible in PD Mode)
6
QUALITY
Improves the Color Resolution by reducing the image frame rate, respectively vice versa.
7
FREQUENCY
It serves for selection of the Transmit Frequency which also depends on the Color Box
position.
8
WMF
(Wall Motion Filter)
Used to eliminate Doppler “noise” that is caused by vessel wall or cardiac wall motion.
(CFM,PD)
9
PRF
By touching toward up the PRF increases. By touching toward the PRF decreases.
10
ZOOM
Image magnification (PAN-Zoom) in read- and write mode.
