Volume Tools
Fig. 17-5. Volume circle.
The volume circle should completely surround the data you want to quantify.
To resize the circle, click on it to select it, then position your cursor on the
circle border and drag.
Volume Labels
When you first create your volumes, they will appear unlabeled. You can
display the volume labels using the Show/Hide Volume Labels command on
the Volume menu or toolbar.
Your volumes will have default labels U1, U2, U3, etc. The “U” stands for
unknown, as distinguished from standard and background volumes (see
below). The number indicates the sequence in which it was created.
Note:
If you change a volume’s type (e.g., change an unknown to a standard),
any subsequent volumes of the original type will be renumbered. For
example, if you create volumes U1 and U2, and then designate U1 as a
background volume, U2 will be renumbered U1.
You can rename a volume by double-clicking on it and entering a new name
in the pop-up box.
Other General Features of Volumes
The volume you create will initially have a green border, which indicates that
the volume is selected. If you click elsewhere on the image, the border will
change to blue, indicating that the volume is deselected.
