5.11.11.3 Smart V Vocal
Basic Procedure
1. Acquire necessary 3D/4D data.
2. Tap [Smart-V][Smart V Vocal] on the touch screen to enter Smart V Vocal interface, and the
system is in the “Reference Line” status;
3. Rotate the knob under [Slice Num] to set the number of slices.
4. Set the reference line on one of the three MPRs by using the trackball and the set keys.
5. Rotate the knob under [Trace Mode] to select the desired trace mode.
6. Trace the contour on slices. The trace should cross the two round points of the reference line.
Tap [Next Slice]/[Previous Slice] to go to the next or previous slice.
7. After contours are traced on all the slices, tap [Calc Vol], and the system starts to calculate;
8. Auto calculation is finished:
There are yellow solid curves enclosing target region on each MPR image (A, B, C) window.
3D image (VR) displays image of the target region in red;
The calculation result is displayed on the lower left part of the screen.
9. Modify the contour of the calculated area and recalculate its volume, if necessary.
For details, see 5.11.11.6 Operation Controls.
10. Calculate the volume of the shell.
Tap [Shell] and rotate the knob under [Shell Thickness] to set the shell of the contour and its
thickness. The calculation result is displayed on the lower left part of the screen.
NOTE:
To ensure the accuracy of the result, please make sure that the traced contour has
entirely enclosed the target and is approximate to the target before using the Smart
Volume function.
5.11.11.4 Smart V Parallel
The operation of Smart V Parallel is the same as those of Smart V Vocal.
5.11.11.5 Result Display
After calculation, the following result will be displayed on the lower left part of the screen.
Whereas, L, W and H represent 3 diameter lengths of the fitting ellipsoid.
V represents calculated volume value.
MG represents Mean gray value; VI represents Vascularization Index; FI represents Flow Index; VFI
represents Vascularization Flow Index.
5.11.11.6 Operation Controls
Edit ROI (Only for Smart-V ROI)
Adjusting the ROI box size and position is to select the volume data needed for calculation.
1. Tap [Edit ROI] on the touch screen to be on (blue highlighted status).
2. Select a desired MPR image by tapping [A], [B] or [C].
3. Roll the trackball to adjust ROI position and size, and press <Set> to switch between the adjusting
status, or you can rotate <4D> knob on the control panel to adjust section image position.
