Image Optimization 5-39 
Tips: changing the view direction only changes the 3D/4D image; images of the 3 
sections do not change. 
 Probe 
A 2D imaging probe can be applied for Smart 3D imaging, however, to realize static 
3D imaging or 4D imaging, a volume probe should be selected. 
 Sectional plane 
The principle of 3D imaging is to render a 3D image from multiple 2D image 
information. The following describes the spatial relation of 3 sectional planes (A, B 
and C) and the 3D image. 
The sectional plane can be viewed in the following status: 
z  3D image viewing status of Smart3D 
z  3D image viewing status of Static 3D 
z  Real time 4D or frozen 4D status 
In the quad display format view, the screen displays A, B, C 3 sectional planes and 
the 3D image. 
 
A, B, C section images are illustrated as the following sections of 3D image. 
 
z 
Section A: corresponds to the 2D image in B mode. Section A is the sagittal 
section in fetal face up posture, as shown in the figure A above.
