Chapter 4 Diagnosis Modes
Baseline / Filter
Baseline
If you rotate the Soft Menu dial-button [6] clockwise, the baseline rises.
In Color Doppler Mode, the color bar indicates the direction and speed of blood flow. Relative
to the baseline in the centre, the red color indicates the direction and speed of the blood flow
towards a probe. By contrast, the blue color indicates the direction and speed of the blood ow
away from a probe.
Filter
The filter is an electrical filter used to eliminate low-frequency Doppler signals caused by the
motion of vessel walls. Adjust the Cuto Frequency to remove the Doppler signals for which the
frequencies are lower than the Cuto Frequency from the screen.
Select a value between F 0 and F 3 by pressing the Soft Menu dial-button [6]. The value will be
displayed on the monitor.
Color Map
Sets the Post Curve of an image. Select a type between 1 and 14 by rotating Soft Menu dial-button [1].
Balance
Adjust the range of color image display by comparing the Gray Level of the 2D image with the Doppler
signal values of the color image. As the Balance value increases, the color image appears, even in
regions with a high Gray Level in 2D image (bright regions), expanding the range of the color image.
Use the Soft Menu dial-button [2] to choose a Balance value between 1~16.
Color Format
Sets C Mode to use. Select Color + B/W, B/W Only or Color Only by rotating the Soft Menu dial-button [3].
Color Mode
Sets the color display. Select Velocity or Vel + Var by rotating the Soft Menu dial-button [4]. If Velocity
or Vel+ Var is selected, a numeral representing the number of a color scale is indicated above and below
the color bar.
