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, and the item becomes “Edit On” in blue.
 Tap [Add] and then trace an enclosed area manually, and the area to be calculated will be enlarged
to include the traced area. The original contour is yellow, and the new contour is blue.
 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. The original contour is yellow,
and the new contour is blue.
 Rotate the knob under [ROI Range] 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, and the item becomes “Edit On” in blue. Then you can
modify the contour on each slice.
 Tap [Win Format] to select the display format of slices.
 Tap [Update Vol] to calculate the volume based on the new contour.
MPR Thickness
Rotate the knob under [Thickness] to adjust the thickness of MPRs. The bigger the value is, the more
the thickness information appears.
Trace Mode
 Trace
1. Rotate the knob under [Trace mode] to select [Trace].
2. Rotate the trackball to place the cursor and press right <Set> key to fix the starting point, move the
cursor along the target to trace the outline, and press right <Set> twice to finish tracing. During
tracing, press left <Set> to cancel a series of tracing, or you can roll the trackball backwards to
delete latest tracing.
Press <set> key to display “Cancel” status on the track ball region, move the track ball to cancel the
trace.
 Spline
1. Rotate the knob under [Trace mode] to select [Spline].
2. Rotate the trackball to place the cursor and press right <Set> key to fix the starting point, move the
cursor along the area of interest and press right <Set> to anchor several reference points; or press
left <Set> to cancel a series of lines.
3. Press <Set> twice to set the end point of the spline.
Press <set> key to display “Cancel” status on the track ball region, move the track ball to cancel the
spline.
 Smart Trace
1. Rotate the knob under [Trace mode] to select [Smart Trace].
2. Rotate the trackball to place the cursor and press right <Set> key to fix the starting point, move the
cursor along the target to trace the outline, and press right <Set> key twice to finish tracing. During
tracing, press left <Set> to cancel a series of tracing, or you can roll the trackball backwards to
delete latest tracing.
Press <set> key to display “Cancel” status on the track ball region, move the track ball to cancel the
