Trace Sensitivity
DescriptionAdjust the trace to follow the waveform for signal strength.
AdjustingPress the left or right arrow key to select value.
Va l u e sFrom 0 to 40. 
BenefitsIf the signal is very faint, changing the Trace Sensitivity will allow 
the system to lock onto that signal strength. 
PW/CF Ratio

Continuous Wave Doppler (CWD)
Allows examination of blood flow data all along the Doppler 
Mode cursor rather than from any specific depth. Gather 
samples along the entire Doppler beam for rapid scanning of the 
heart. Range gated CW allows information to be gathered at 
higher velocities.
There are two CW Doppler operating modes: Steerable and 
Non-Imaging.
Steerable
Allows viewing of the B-Mode image to position the...

Non-Imaging
Provides only Doppler Spectrum and Audio for ascending/
descending aortic arch, other hard-to-get-to spaces or higher 
velocities.
Requires a single CWD probe and probe adapter.
Works with the P2D and P6D probes.

Activating CW Doppler
To activate CW Doppler Mode, press CW. 
The Doppler spectrum displays along with the B-Mode image. 
(Steerable CW Doppler, NOT Non-Imaging CW Doppler). The 
cursor changes to a Doppler cursor.

3D Acquisition
Acquiring a 3D Scan
To acquire a 3D scan, 
1.  Optimize the B-Mode image. Ensure even gel coverage.
2.  Press the 3D control panel key. Two screens appear. 
NOTE:  Set appropriate values for Acq Mode and Scan Plane. Also, 
set the scan distance before scanning. 
3.  To start acquiring the image, press ‘L’ (the left split screen 
key). 
4.  To perform a parallel scan, scan evenly. To perform a sweep 
(fan) scan, rock the...

Manipulating the Volume of Interest
Imagine you are able to manipulate the 3D volume of interest 
(VOI) in your hand. The 3D VOI is a tangible anatomical object 
that you can see and manipulate easily using the Trackball and 
Set control panel keys. 
Practice positioning the pointer at different places within the 3D 
VOI. Highlight different colors (white, red, yellow, or green). 
Press Set to select a VOI for manipulation....
