How can I take a 3D image of the fetus face?
First of all, the pregnancy weeks should be appropriate.
The best time to take image of the fetus face is pregnancy of 16W-35W.
At this time, the fetus head is not too big, while the amniotic fluid in the
uterus is sufficient, and the light transmission is good. Thus it is easy to
take a clear three-dimensional image of the fetus.
When the pregnancy week is too small (before 16W), for the sake of
your fetus' health and safety, try to reduce the shooting times.
When the pregnancy week is too large (after 35W), the fetus has grown
up, while the amniotic fluid in the uterus is reduced and the light
transmission is weakened. Thus it is difficult to capture the fetus' three-
dimensional image.
Second, the fetus position should be appropriate.
The ideal position for shooting is that the fetus face is facing the
mother's belly; if the fetus face is facing the mother's back, the fetus
position is not suitable, and it is difficult to photograph the fetus face.
Third, "framing" is critical.
The three-dimensional image content is generated by processing a black
and white two-dimensional image of continuous multi-frames through a
three-dimensional reconstruction algorithm.

images of black and white Continuously multiple 2D
images form a 3D image
Therefore, the content of the three-dimensional image is directly
determined by the content presented on the two-dimensional image.
If the angle of the two-dimensional image is not good or not clear,
the content of the three-dimensional image will not be ideal, so the
"framing" of the two-dimensional image is very important.
