For further details refer to the Voluson® 730Pro / 730ProV Basic User Manual:
•
Chapter 8, CFM Mode (Color Flow Mode)
•
Chapter 9, PD Mode (Power Doppler Mode)
•
Chapter 10, TD Mode (Tissue Doppler Mode)
11
DISPLAY MODE
To select the CFM- Display Mode (V; V-T; V-Pow; Pow-T; or T).
12
SCALE (CFM, TD)
The maximum velocities are displayed above and under the color scale in kHz, cm/s or m/s.
13
LINE FILTER
With “Line Filter” the signals of the neighboring pulses are less weighted for the display of the
actual pulse which considerably improves the detail lateral resolution and signal-to-noise ratio.
14
GENTLY COLOR
Gently means the transition between color and gray scale information.
The embedding of the color into 2D Mode is performed smoothly with less colored splashes.
15
ARTEFACT (on/off)
Switch on/off the artifact suppression.
16
BASELINE
The baseline shift can be used to prevent aliasing in one flow direction similar to the Doppler
baseline shift. There are 8 steps in each direction. (impossible in PD Mode)
17
ENSEMBLE
Controls the number of pulses to constitute one Color- or Power-Doppler line in the display.
18
LINE D.
Determines the line density within the Color-Box.
The lower the line density, the larger the line distance and the size of the color pixels.
19
C-MAP
(PD, TD)
Provides selectability of the color coding for an optimization of the display of blood flow (similar
to the post-processing curves with grayscale 2D scans).
After a selection has been made, the color bar displays the resultant map.
20
SM. RAISE
To select different filter periods for raising velocity.
Filtering of the rise velocity leads to noise suppression.
21
SM. FALL
To select different filter periods for falling velocity.
This filter leads for “prolongation” of the display flow.
22
FLOW RES.
The “Flow Resolution” function controls the axial resolution of color in the display.
It adjusts the axial sample depth of color pixels.
23
BALANCE
The Balance controls the amount of Color display over bright echoes and helps to confine
color within the vessels wall.
24
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 fewer signals than a higher setting)
25
Exit
Press the
EXIT
key on the control panel to exit the CFM, PD or TD Sub menu.
