5-62 Image Optimization
5.11.11.1 Smart V ROI
Basic 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 in blue);
3. Set ROI position and size, and tap [Calc] (after touching the button, the button is highlighted in blue
to indicate the status);
4. 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.
For details, see 5.11.11.6 Operation Controls.
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.
5.11.11.2 Smart V Trace
Basic Procedure
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;
3. Rotate the knob under [Trace Mode] to select the desired trace mode, and trace the contour on at
least two MPRs.
4. Tap [Calc], and 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.
For details, see 5.11.11.6 Operation Controls.
7. 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.
