7.14 Smart Face
Smart Face is only used for obtaining fetal face features, not for confirming a diagnosis.
This feature allows the system to recognize fetal face and remove the shading obstacle data
automatically, then display the face in a recommended viewing angle.
Perform the following procedure:
1. Acquire Static 3D image or frozen 4D single-frame image of fetal face.
2. Tap [Smart Face] to enter the function and the system adjust fetal face angle (fetal head facing
up) automatically and remove the shading obstacle data.
7.14.1 Parameter adjusting
Parameters under Smart Face are similar to those under Static 3D mode.
Tap on the lower-right corner of the [Smart Face] to enter Setup screen.
MixRender
This function is available only under “Surface” mode.
The higher the merge value, the clearer the shading obstacles on the image.
If the value is set 0, no obstacle data will be displayed.
Tap [Face+] to select the levels between 0-3.
Eraser
This function is available only under “Surface” mode.
Clearing effect in the center of the eraser sphere is strongest, and this effect weakens along the
sphere center to the edge.
Tap [For-Rubber] to erase existing data on the screen.
Tap [Re-Rubber] to restore those removed shading data.
• Use [EraseSize] to select the size: Small, Middle, Large.
• Tap [Undo] to undo the operation in sequence and tap [Undo All] to undo all erase effects.
AutoDirect
This feature allow you to optimize to a best observing angle of view within one step.
The recommended angle: fetal head is facing up and the face is at the front with [Direction] to be
up/down.
FaceContact
The higher the value, the more adjacent the VR image is to the fetal face, and the more obstacles
cleared.
The lower the value, the further the VR image is to the fetal face, and the less obstacles cleared.
Select [FaceContact] to adjust the parameter.
