How to Improve 3D Image Quality

X

Consider the direction, division and size of the viewpoint, as well as the visibility of an object.

X

Before acquiring 3D images, adjust the contrast in 2D Mode.

X

If the ROI box is bigger, it takes more time to acquire 3D images. Therefore, set the ROI box to an

appropriate size.

X

To see the 3D scan of a fetus in a frontal view, position the fetal head in the direction of

“Direction Mark”, putting it in the coronal plane. Then scan the fetus from back to abdomen.

X

The 3D image of the fetal face can be more easily found in the coronal plane than in the sagital

plane.

X

In case echo is not generated (ex. amniotic fluid), to determine surface contour, the surfaces of

objects should be insulated with hypo-echoic textures.

X

To obtain a high quality 3D surface, adjust Low-Threshold. As a general rule, do not adjust High-

Threshold; set it to the maximum value of 255.
