Update
Toggles a real-time display with a frozen display during mixed-mode imaging.
For example, if a 2D-mode image is frozen while the Doppler spectrum is in
real-time, pressing the UPDATE key causes the system to display the
2D-mode image in real-time while freezing the spectrum.
Angle
A dual-function control that activates one function when the control is
pressed and another function when the control is rotated.
Rotating the ANGLE control positions the Flow Angle indicator in
relationship to the Doppler cursor.
Pressing the ANGLE control cycles through the active settings for the
Flow Angle indicator. The value of the angle displays in the upper right of
the screen.
CW
Activates the steerable continuous wave (SCW) Doppler function for phased
array transducers.
C
A dual-function control that activates one function when the control is
pressed and another function when the control is rotated.
Pressing the C control initiates Color Flow imaging.
Rotating the C control clockwise increases the gain; counterclockwise
rotation decreases the gain. The range for gain settings is from 0 dB
to 30 dB.
Note: In Power mode, rotating the C control changes the overall gain for Power mode.
C: 2/ 4/ 25
Color or power gain (dB) is indicated by the shaded value.
The gain value for the color image displays as the last number in the Image
Parameter area, at the bottom of the screen.
