7 3D/4D
The higher the merge value, the clearer the shading obstacles on the image.
Tap [MixRender] to select the levels between 0-3. Tap [SubTint] to select the obstacle display color.
If the value is set 0, no obstacle data will be displayed.
Eraser
NOTE:
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.
Rotate [FaceContact] to adjust the parameter.
VR Orientation
Rotate the image quickly. Adjust in VR Orientation: 0°, 90°, 180°, 270°.
7.19 Volume CEUS
It is only to view the microbubbles injection of a certain plane once in the 2D ultrasound contrast
imaging, however it is possible to view stereo microbubbles injection in the 3D ultrasound contrast
imaging.
3D contrast injection imaging is used to characterize focal liver lesions. 3D ultrasound contrast
imaging shows the arrangement of the tumor blood vessels from early phase enhancement to late
phase enhancement and displays the changes of the enhancement type in multi-plane way. There is
also another significant clinical application for 3D ultrasound contrast imaging. It is applied in the
oviduct to judge its clearness.
Perform the following procedure:
1.
Choose the volume probe and the exam mode. Scan the image. Optimize the image. Ensure the
tumor, the lesion, ovary inside the image.
2. Tap [Contrast] to enter contrast imaging in 2D scan mode. Adjust the parameter to obtain the
premium image.
3. Press to enter the acquisition preparation of the volume CEUS. Set the ROI position/
size and VOI. Select the rendering mode. Set the scan angle/quality, etc.
Inject the contrast agent in step 2 or step 3. Turn the timer on. Obverse the contrast image.
