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.
10. Calculate the volume of the shell.
Tap [Shell] on the touch screen to select the shell type, select [Thickness] and rotate [Angle] to
set the 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.
7.12.2 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.
7.12.3 Operation Controls
Edit
After the calculation, you can modify the contour of the calculated area and recalculate its volume.
• For Smart-V ROI and Smart-V Trace:
– Tap [Edit off] to enable the editing function.
– Tap [Add] and then trace an enclosed area manually, and the area to be calculated will be
enlarged to include the traced area.
– Tap [Delete] and then trace an enclosed area manually in the already calculated area, and
the area to be calculated will be narrowed down to exclude the traced area.
– Tap [ROI Range] and rotate [Angle] to set ROI range. The operator can only trace the
contour inside the ROI.
– Tap [Undo] or [Redo] on touch screen to undo or redo previous editing. Tap [Undo All] to
undo all editing steps.
– Tap [ReCalc] to calculate the volume based on the new contour.
• For Smart-V Vocal:
– Tap [Edit off] to enable the editing function. Then you can modify the contour on each
slice.
– Use [Win Format] to select the display format of slices.
– Tap [Update Vol] to calculate the volume based on the new contour.
MPR Thickness
Tap [Thickness] and rotate [Angle] to adjust the thickness of MPRs. The bigger the value is, the
more the thickness information appears.
