2. Sample Gate Overlay: The wireframe represents the area that the transducer will acquire image
data. The area between the two horizontal green lines of the wireframe represents the sample gate.
Use the controls on the Control Panel (such as Gate Size) to adjust the sample gate. For more
information, refer to PW Doppler and PW Tissue Doppler Controls on page 139.
3. Display Map
4. PW Doppler Data Window: Displays the sample volume image data that is defined in the B-Mode
scout w indow. This window has the following properties:
The most current data begins at the right side of the window.
o
The t railing data in the clip acquisition buffer extends to the left.
o
The horizontal line that runs across this window is the PW Doppler baseline, and divides the
o
spectral display into positive velocities (flow moving towards the transducer) and negative
velocities (flow moving away from the transducer).
5. Doppler Scale
Blockout Zones
The block out zones are areas where the transducer does not retrieve reliable data. Their size and
configuration are based on a number of factors. They are marked as blue areas and are an indication to
place the sample volume away from these areas.
PW Doppler and PW Tissue Doppler Control Panel Interface
When PW Doppler Mode or PW Tissue Doppler Mode is selected and image acquisition is running, the
Control Panel shows the following interface:
