5-32 Image Optimization
z
Fan scanning
Rotate the probe once from the left to the right side (or from the right to the left) to
involve the whole region desired. See the following figure.

Method
Function: select the image acquisition method.
Selection: Fan, Linear.
Linear mode: during the sweep, the probe may not be
moved parallel.
Fan mode: in this mode, the probe must be moved to a
position where you can clearly see a middle cut of the
object you want to scan and render. Tilt the probe to about
30 degrees until the object you want to scan disappears.
Start the acquisition and tilt the probe over a distance of
around 60 degrees until the object disappears again.
During the sweep, the probe may not be moved parallel,
just tilted.
Tips: the speed is related to scanning distance or angle.
Distance
Function: to set the distance the probe covered from one
end to the other end during a linear sweep.
Range: 10-200mm, in increments of 10mm.
Angle
Function: to set the angle the probe covered during a fan
sweep.
Range: 10-80°, in increments of 2°.
Reset Curve
To reset the VOI edge line to be linear.
Render
Gray/Inversion
Surface
Function: set Surface as 3D image rendering mode.
This is helpful for surface imaging, such as fetus
face/hand or foot.
Tips: you may have to adjust the threshold to obtain a
clear body boundary.
