13 Change scale (PRF) Velocity scale determines pulse repetition
frequency. If the sample volume gate range
exceeds single gate PRF capability, the
system automatically switches to high PRF
mode. Multiple gates appear, and HPRF is
indicated on the display.
14 Transparency Map Allows to select specific transparency map
15 Focus Position Increases the number of transmit focal zones
or moves the focal zone(s) so that you can
tighten up the beam for a specific area. A
graphic caret corresponding to the focal zone
position(s) appears on the right edge of the
image.
16 Power output Optimizes image quality and allows user to
reduce beam intensity. 10% increments
between 0-100%. Values greater than 0.1 are
displayed.
17 Wall Filter Wall Filter insulates the Doppler signal from
excessive noise caused from vessel
movement.
18 Map Compress When you increase the value, high velocity
elements in the map are compressed so that
the map darkens. When you decrease the
value, low velocity elements in the map are
compressed so that the map lightens.
19 Accumulation Accumulation enhances the flow in an image.
Off-Infinite: Infinite provides the same result as
applying CINE Capture to a B-Flow CINE clip.
20 Sample Vol Adjust the control to adjust the sample volume
gate on the Color Flow image.
21 Flash Suppression Activates/deactivates Flash Suppression, a
motion artifact elimination process.
