Spectral Doppler Mode Controls
(Pulsed Wave, Continuous Wave, and Tissue Doppler)
Note: Continuous Wave Doppler imaging is available only on ZS3 systems equipped with
the Echocardiology or Advanced Vascular Options.
Doppler Control
Description/Use
Softkeys OLED
controls
While Pulsed Wave (PW), Continuous Wave (CW), or Tissue (TDI) Doppler are
active, the Softkeys at the back of the console contain the optimization and
navigation controls specific to Spectral Doppler Imaging.
Pressing OLED #1 toggles through multiple pages of controls.
Priority
Press the Priority button to gain access to OLED controls assigned to modes that are
‘ON’ but do not have priority.
• For example, if PW Doppler is ON, the OLED controls will reflect PW Doppler
controls as the active mode. The user can press the Priority button to toggle to
B-Mode which will change the OLEDs to B-Mode without having to turn off Color
Doppler.
* Indicates that this control is also available in retrospective processing.
Gain*
Adjust Gain by rotating the outer ring of the D-Mode button.
There are two mechanisms to invoke CW and TDI:
•
They can be assigned to Programmable Function Keys in Setup / Keys. When
invoked this way the programmable keys act as CW or TDI hard key and the
“D” mode button is dedicated to PW.
•
They can have shared access with PW through the “D” mode button. When
invoked, the default Doppler mode is determined by preset. While Spectral
Doppler is active, a soft key (OLED) toggles between PW, TDI, and CW.
Subsequent invocations of Spectral Doppler invoke the last used Doppler
mode.
The optimization controls available in CW and TDI are generally the same as in PW.
See the Spectral Doppler section (above) for details.
CINE Controls
The ZS3 Ultrasound System contains an Extended Cine buffer which does not ‘flush’ with
mode changes, providing the user with access to data typically lost from the cine buffer
when the user freezes the image or changes modes.
The CINE controls are accessed via the Priority Key or by Pointing to and selecting CINE
on the onscreen Trackball Priority ICON with the Trackball and Set Keys.
