Image Optimization 5-63
5.11.8 Smart 3D
The operator moves the probe to change its position/angle when performing the scanning.After the
scanning, the system carries out image reconstructure, and then displays a single frame of 3D image.
If the system is only set up with Smart 3D module, press <3D> to enter Smart 3D imaging mode.
If the ultrasound system is equipped with Smart 3D module, press <3D> to enter Smart 3D imaging.
Smart 3D is an option. 4D probe does not support Smart 3D imaging.
5.11.8.1 Smart 3D Procedures
NOTE:
In Smart 3D image scanning, if the probe orientation mark is oriented to the operator’s finger,
perform the scan from right to left in linear scan, or rotate the probe from left to right in rocked
scanning. Otherwise, the VR direction will be wrong.
To perform Smart 3D imaging:
Select the proper probe and exam mode; make sure there is sufficient gel on the probe for
scanning.
Obtain a 2D image, and optimize the image if necessary.
Press <3D> on the control panel to enter Smart 3D mode.
Adjust ROI size and position and the position of VOI.
NOTE:
To define a ROI, please remove the useless data as to reduce the volume data and shorten
the time for image storing, processing and reconstruction.
Select the render mode. Set the scan method and the movement of the probe (angle and distance).
Press <Update> to start 3D imaging.
The system enters into 3D image review status when the acquisition is completed; or, you can finish
the acquisition ahead by pressing <Freeze> or <Update> on the touchpad.
In image review status, you can perform operations like VOI setting, parameter adjustment,
commentss, image saving, image cutting, etc.For details, please refer to Chapter
Exit Smart 3D
Press <Update> or <Freeze> to return to Smart 3D acquisition preparation status.
Or press <B> or <3D>
to exit the mode.
5.11.8.2 Smart 3D Acquisition Preparation

Parameter
Note
Method
Function: to select the probe moving method.
Selction: Fan, Linear.
Fan 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.
Tips: the scan speed is determined by scan angle or distance.
