Expected Result(s)
Displays a menu of color map options.
Use the trackball to point to a color map and press
SELECT
to activate the desired color map.
Each color map is assigning different color hues to
different velocities.
Starts cine loop acquisition.
Expected Result(s)
Enables the adjustment of the transmission frequency to
control the sensitivity or the level of penetration.
The selected frequency is displayed in the status
window.
Adjusting Frequency may affect Sample Volume and
LVR settings.
Smooths the image by averaging collected data along
the same radial line.
An increase of the radial averaging will reduce noise, but
this will also reduce the radial resolution.
Smooths the image by averaging collected data along
the same horizontal line.
An increase of the lateral averaging will reduce noise,
but this will also reduce the lateral resolution.
