SSI-6000/SSI-5800/SSI-5500/SSI-5500BW
Digital Color Doppler Ultrasound System
8.3.5 TDI Gain
Properly adjust the TDI gain to ensure that the color flow is continuous
but no color speckle is present.
Turn the D GAIN knob clockwise / counterclockwise to increase / de-
crease the TDI gain.
Remarks:
• The TDI gain value is displayed on the screen at the Color Image Info area (GN).
• It is possible to change the TDI Gain only when the TDI mode is active.
8.3.6 Persistence
PERSIST
Similar to the persistence in the B mode, adjust the persistence value to enhance
the smoothness of the color image.
• go to the TDI menu (Figure 6.2), highlight PERSIST.
• use the LEFT/RIGHT keys to decrease/increase persistence value.
Remark:
• The persistence value is displayed on the screen at the Color Image Info area
(the P in C/P).
8.3.7 Color Map
C MAP
Similar to the Color Map in the CDI mode, this function select the method for the
color-coding of the display of color flow.
The Color Map setting is adjustable in the real time mode as well as the freeze
mode.
• highlight C MAP in the context menu.
• use the LEFT/RIGHT keys to adjust the color map method.
Remark:
• The Color Map method is displayed on the screen at the Color Image Info area
(the C in C/P).
8.3.8 TDI Power
POWER %
Similar to the acoustic output power in the B mode, the value of the output power
in the TDI mode should be kept as low as reasonably achievable.
