Chapter 4 Diagnosis Modes

Acquiring 3D/4D Images

1. Specify the location and size of the ROI Box as desired.

2. Set the required parameters in the 3D Stand By screen on the touch screen.

X

After selecting the menu tab for 3D/4D Modes, select View Mode à Rendering Preset à Userset

à the desired item.

3. Press the Freeze or Set button on the control panel. The system will start acquiring 3D images.

4. Once 3D images are acquired, the 3D View or 3D XI screen is displayed. The 3D View or 3D XI

indication appears in the upper left corner of the screen.

X

If a horizontally-reversed 3D image is obtained, the image will also be shown horizontally-

reversed in 3D View or 3D XI.

5. Optimize the acquired images as needed for diagnosis. Press the 3D/4D button to acquire 3D

images again.

Tips!

How to Improve 3D Image Quality

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

X

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

X

The bigger the ROI box, the slower the rendering speed. Therefore, set an appropriate ROI box

size.

X

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

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

X

The 3D image of a fetal face can be more easily located in the coronal plane than in the Sagittal

plane.

X

To determine surface contour, subjects such as amniotic fluid that do not generate echoes

should be insulated with hypo-echoic textures.

X

To obtain a high quality 3D surface, adjust the Low Threshold value. The general rule is not to

adjust High Threshold; set it to the maximum value of 255.

NOTE: You can cancel a scan job by pressing the Exit button.
