Switch on / off the “Coded” [Harmonic Imaging] function in
2D mode.
brightly illuminated: Harmonic Imaging is active (receiving frequency is the double of
the transmitted frequency).
Weakly illuminated: Harmonic Imaging can be used, with the selected probe, but is not
active (the last adjusted transmitting frequency is active).
Not illuminated: Harmonic Imaging cannot be used with the selected probe.
Use the [Harm.Frequ.] control to adjust the range of the
frequency. Three settings are possible: high, mid, low
Remarks:
•
The Harmonic frequency setting is displayed in 2
nd
line of the B mode Image Info area.
6.2.10 β-View (Beta View)
The “Beta View” function allows the adjustment of the Volume O-Axis position of 3D probes in
2D mode. The green line in the displayed symbol indicates the position of the acoustic block. +
and - defines the corresponding sweep direction on the screen.
Rotating the control changes the position of the acoustic block. Pressing the control moves
the acoustic block back to 0˚, which is the central 2D-mode plane.
Remarks:
•
The [Beta View] function is only available with certain 3D probes.
•
The symbol is only displayed when the position is not 0˚.
•
A short beep sounds, if the min. or max. axis position is reached.
6.2.11 Focus and Frequency Composite (FFC)
Focus and Frequency Composite (FFC) technology utilizes two different transmit frequencies
and two different focal ranges in the 2D image. This function combines a low frequency to
increase the penetration and higher frequency to keep a high resolution. It reduces speckle
and artefacts in the 2D image to facilitate the examination of difficult-to-scan patients.
Switch on/off the [FFC] Focus and Frequency Composite function in 2D mode.
