Advantage of the Virtual Convex mode: The scan area is increased in relation to the linear
display by steering the ultrasound lines on the edge of the probe.
Selection of Linear- or Virtual Convex mode display.
Remarks:
•
These keys appear automatically in the 2D mode menu, if the selected probe is capable
of Virtual Convex mode.
•
Virtual Convex mode is also possible in Doppler- and Color mode without restrictions.
Wide Sector is the equivalent of Virtual Convex Mode for curved array transducers.
Advantage of the Wide Sector: The scan area is increased in relation to the curved display by
steering the ultrasound lines on the edge of the probe.
Selection of Curved- or Wide Sector display.
Remarks:
•
These keys appear automatically in the 2D mode menu, if the selected probe is capable
of Wide Sector mode.
•
Wide Sector mode is also possible in Doppler- and Color mode without restrictions.
Coded Excitation (CE) improves image resolution and penetration in the far field. This allows
to use a higher frequency on technically difficult patients.
Switch on/off the [CE] function in 2D mode.
Remark: Activating [CE] lowers the frame rate.
In this special 2D mode, pulses are transmitted not only perpendicularly to the acoustic
window, but also in oblique directions. 3, 5, 7, 9, or 11 angles are correlated for one frame.
The advantages of CrossBeam Compound Resolution Imaging (XBeam CRI) are enhanced
contrast resolution with better tissue differentiation and clear organ borders. Also vessel walls
and tissue layers are emphasized for easier recognition.
Switch on the [XBeam CRI] function in 2D mode and change the level of the
contrast resolution using the [+] and [-] keys.
