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.
NOTE:
• To ensure the accuracy of the result, ensure that the VOI position and size setting has entirely
enclosed the target and is approximate to the target before using the Smart Volume function.
• Smart Volume is not available for Smart 3D image.
7.12.1 Basic Procedure
Smart-V ROI
Perform the following procedure:
1.
Acquire necessary 3D/4D data.
2. Tap [Smart-V] > [Smart V ROI] on the touch screen to enter Smart V ROI interface, and the
system is in the “Adjust ROI” status ([Edit ROI] button is highlighted).
3. Set ROI position and size.
a. Select a desired MPR image by tapping [A], [B] or [C].
b. Roll the trackball to adjust ROI position and size, and press <Set> to switch between the
adjusting status.
4. Tap [Calc], the system starts to calculate.
5. 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.
6. Modify the contour of the calculated area and recalculate its volume, if necessary.
7. Calculate the volume of the shell.
Tap [Shell] and rotate the knob under [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 ROI position and size setting has
entirely enclosed the target and is approximate to the target before using the Smart Volume
function.
Smart V Trace
1. Acquire necessary 3D/4D data.
2. Tap [Smart-V] > [Smart V Trace] on the touch screen to enter Smart V Trace interface, and the
system is in the “Trace On MPRs” status.
