Q9 Digital Color Doppler Ultrasound System
35
DIST
In 2D (B and Color) cine mode, DIST-key is used for Distance
measurement.
In Doppler cine mode, press DIST-key one time to measure Flow
Velocity.
In M cine mode, press DIST-key for Distance measurement
TRACE
In
2D
mode,
TRACE-key
is
for
measurement
of
Area/Circumference with tracing method.
In Doppler cine mode, this key can be used to calculate PI and
RI ,and can envelope automatically
CALC
Use this key to activate calculation packages under different
applications. This feature supports the optional OB, GYN, Vessel,
Urology, Cardiac, Small parts, Pediatrics, Carotid Abdomen and
General calculation packages. Refer to Measurement & Calculation
section for details.

Image Controls
MENU
This key provides multiple functions according to the active mode on
the screen.
In real-time mode, it accesses the Soft- Menu that corresponds to
each mode. Press MENU-knob for second time to select the item
and adjust the parameters. Press MENU-knob for third time to
exit from current item. Rotate the MENU- knob to select the
item
TGC Sliders
Manipulate the TGC (Time Gain Compensation) with 8 pairs of
sliders.
DEPTH
Press this paddle up/down to change the image depth of view.
PRF
Press this paddle up/down to change PRF setting in the color or
Spectral Doppler modes.
BASELINE
Use this paddle to control the zero velocity Baseline shifting. In
Color mode, the maximum detectable velocity is stretched. In
Spectral Doppler mode, the spectrum is wrapped around.
FOCUS
Use this paddle to move the transmitted focal position up or down
in any mode while B mode is active. The transmitted focal
position remains at the center of the Doppler Sample Volume Gate
in spectral Doppler mode, and at the center of the CROI in color
mode.
