Method
Function: select the image acquisition method.
Selection: Fan, Linear.
Linear mode: during the sweep, the probe may not be
moved parallel, the speed at which you scan should be
constant, about 2cm/s.
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. The speed is about 10°/s-15°/s.
