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
HD-Flow 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 PD MODE
key to adjust the Bi-Directional Angio Gain
Rotate the C MODE
key to adjust the Tissue Doppler Gain.
3
STEERING
Beam Steering is only possible with linear probes in CFM, PD and HD-Flow Mode.
4
2D+2D/C (PD, HD-Flow
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.
5
INVERT The color of the color wedge inverts around the baseline. (impossible in PD Mode)
6
ZOOM Image magnification (PAN-Zoom) in read- and write mode.
7
QUALITY
Improves the Color Resolution by reducing the image frame rate, respectively vice versa.
8
WMF (Wall Motion Filter)
Used to eliminate Doppler “noise” that is caused by vessel wall or cardiac wall motion.
(CFM,PD, HD-Flow)
9
PRF
By touching toward up the PRF increases. By touching toward the PRF decreases.
10
THRESHOLD
After FREEZE you can adjust the Color Threshold. It eliminates small color noise or motion
artifact signals in the color image. (small number cuts off less signals than a higher setting)
11
DISPL. MODE To select the CFM- Display Mode (V; V-T; V-Pow; Pow-T; or T).
