Image Optimization 5-61
3Slice
1. Select [Tool][3D Layout] tab on the touch screen, then tap [3Slice].
2. Tap [A]/[B]/[C]/[3Slice] on the touch screen to select the reference plane.
3. Roll the trackball to view sectional images as necessary. Rotate <M>, <PW>, <C> to perform axial
rotation or rotate the <4D> knob to adjust the nearest VOI section (cut plane) position.
5.11.10 3D Reference Point
The function enables operators to define one or more reference points on MPRs, which are then
projected to VR image. It is helpful for operators to better understand the corresponding spatial
relations of VR image and MPRs.
1. Select the [VR][3D Ref] tab on the touch screen.
2. Tap [Input] on the touch screen, and a green cross mark appears on the screen.
3. Move the mark to the desired point and press the <Set> key to set the reference point.
You can move the cursor onto the reference point and use the trackball and the <Set> key to move
the reference point.
4. Tap [Display] to select the display mode.
Point Only: only the reference point is displayed.
H Line: The reference point and the horizontal line crossing the reference point are displayed.
V Line: The reference point and the vertical line crossing the reference point are displayed.
5. If necessary, tap [Delete] to delete the corresponding reference point.
6. After the four reference points are defined, you can Tap [Delete All] or [Hide All] to delete or hide all
the reference points.
7. Tap [Return] to exit.
5.11.11 Smart Volume
The system provides three fast volume calculation methods that can be used to calculate the volume of
tissue structure or lesions. The three methods are as follows.
Smart-V ROI: The method uses computer technology to define and enclose a boundary of the target
within the ROI area (the computer technology allows the ultrasound system to fit an ellipsoid that can
be most approximate to the target) and then calculate this volume. It can be used to measure the
volume of mass, gestational sac, bladder or gall bladder.
Smart-V Trace: The method uses computer technology to enclose a boundary of the target traced by
the operator and then calculate this volume. It can be used to measure the volume of endometria or
cerebellum.
Smart-V Vocal: The operator traces the boundary of the target on planes generated by rotation. Then
the system fits a 3D contour based on the contours traced by the operator, and calculate this volume. It
can be used to measure the volume of targets except for those in long and thin shape.
Smart Volume and Smart V Trace are optional, and not available in Smart 3D mode.
CAUTION:
Smart Volume result is provided for reference only, not for confirming a
diagnosis.
