The DICOM Viewer provides for copying segmented structure surfaces in the MPR Reconstruction and Volume Reconstruction windows. You can copy a segmented structure surface:
-
in one study series;
-
in a merged study series.
To make a copy of a segmented structure surface in a single study series, proceed as follows:
-
On the segmented structure panel, select the surface you want to copy.
-
Click the Duplicate surface
button on the segmented structure panel or place
the cursor over the structure, click the right mouse button and choose the Duplicate
surface point in the right-click menu.
On the segmented structure list, you will see a copy of the surface with a "surface copy" note. The name of the surface copy, as well as the name of any structure without a structure mask, is shown in italics.
To make a copy of a segmented structure surface in a merged series, proceed as follows:
-
On the segmented structure panel, select the surface you want to copy.
-
Click the Duplicate surface
button on the segmented structure panel or place
the cursor over the structure, click the right mouse button and choose the Duplicate
surface point in the right-click menu.
-
In the Layer selection (see Fig. 6.13), select from the drop-down list the layer where you want to place the surface copy.
-
Click OK to copy the surface to the selected layer or CANCEL to cancel.
On the segmented structure panel for the layer selected, you will see a copy of the surface with a "surface copy" note. The name of the surface copy, as well as the name of any structure without a structure mask, is shown in italics.
To move the copied surface manually, activate the tool Surface positioning 
by clicking
the left/right/middle mouse button. To continue work with this tool, use the button with
which the tool was activated. To learn more about tool control, see Section 1.14. Move the
surface on the plane of the screen, holding the mouse button with which the tool was
activated.
To scale the surface, move the mouse up and down while holding the Ctrl key (or the Command key for macOS) and the button with which the tool was activated.
To rotate the surface around its center, move the mouse while holding the Alt key (or the Option key for macOS) and the button with which the tool was activated.
To create a segmented structure for a surface, place the cursor over the copy of the surface, click the right mouse button and choose the Create mask by surface point in the right-click menu.
The things you can do with the surfaces and structures on the segmented structure list are described in Section 6.4. The surfaces you have built or copied may be exported or imported. For details on export and import of surfaces and structures, see Section 6.7. The procedures of saving and opening segmentation and DTI projects are described in Section 6.11.
