Primary
Colorize Optimizes contrast resolution by activating the current
colorization map, and overlaying the grayscale image.
To change the active map, turn the color rotary control
just under the Colorize touch control.
Focal Zones Selects transmit focal zones for sector transducers. The
preset and the transducer determine the available
number of focal zones. A caret appears on the screen
for each selected focal zone. With two focal zones
active, the frame rate decreases.
Focus Repositions the acoustic depth of the 2D focal zone,
indicated by carets.
Frequency Fusion Optimizes frequencies for penetration, texture, or
resolution. Changes are reflected in the Frequency
Fusion icon and on the process line displayed at the top
left corner of the screen in Cardiac presets.
Frame Lock Locks or unlocks the Integrated Backscatter (IBS)
imaging frame rate to the video frame rate. The values
are on and off. It is on by default. Applies to IBS, 2D,
and AD.
IPower Sets the transmit power for Contrast TCE-3 Impulse
Imaging.
Harmonic Fusion
(Touch Control)
Activates Harmonic Fusion for imaging tissue.
Activates Harmonics for the 2D image only. Available
only with a harmonics-ready transducer, such as the s3,
s4, s8, 11-3L, c3540, OmniPlane III, or x4. Not
available when the image has been frozen using the
key.
