
Render Mode
Parameter Description
Gray/Inversion
Surface
Function: set Surface as the VR rendering mode.
This is useful for surface imaging, such as fetus face,
hand or foot.
Tip: you may have to adjust the threshold to obtain a clear
body boundary.
Max.
Function: set Max. as the VR rendering mode. Displays
the maximum echo intensity in the observation direction.
This is useful for viewing bony structures.
Min.
Function: set Min. as the VR rendering mode. Displays the
minimum echo intensity in the observation direction.
This is useful for viewing vessels and hollow structures.
X-ray
Function: set X-ray as the VR rendering mode. Displays
the average value of all gray values in the ROI.
X Ray: used for imaging tissues with different internal
structures or tissues with tumors.
The above four rendering methods can be applied to both gray and
inversion modes.
Where inversion means to invert the grayscale of the image, so as to
enhance observation for low-echo regions, applicable for vessels, cysts,
etc.
When the function is turned on, the rendering mode parameters change
to the corresponding inverse parameters.
Rotate an Image
The system supports the following rotation modes:

Auto rotation
(1) In 3D viewing mode, tap [Auto Rot.] and the system enters the automatic rotation
preparation state.
(2) Select [Direction] to be [Left/Right] or [Up/Down] to set the auto rotation
direction.
(3) Set the Start position and End position:
