Compound
Compound is a process of combining three (default) or five
frames from different steering angles into a single frame. The
combined single image has the benefits of reduced speckle
noise, reduced clutter, and continuity of specular reflectors.
Therefore, this technique can improve contrast resolution.
Compound is available with all curved and flat linear probes.
Compound is on by default.
Using compound
1. Press Compound .
A three frames compounded image is produced.
2. To change the number of compounded frames, adjust
Compound frames on the Touch panel. Three or five
frames can be selected.
Virtual Convex
Virtual Convex allows a wider FOV in the depth and aims to
enhance image quality, in particular on linear probes.
B-Flow
B-Flow provides an intuitive representation of non quantitative
hemodynamics in vascular structures. B-Flow enables
visualization of complex hemodynamics and highlights moving
blood and tissue. There are no artifacts such as bleeding,
blooming, or aliasing.
B-Flow is available with all probes except TEE probes.
Using B Flow
1. While in Color flow, press B-Flow .
2. Adjust Flow speckle . Increased Flow speckle enhances
hemodynamics.
The greater the speed, the better the image scatter density and
size. If the scan direction is the same as the flow direction, then
the image scatter is elongated; if the scan direction is the
opposite as the flow direction, then the image scatter is tighter.
Therefore, have the scan direction opposite to that of flow
direction. Switch the way you hold the probe, with the probe
