Regions of Interest Functions

Regions of Interest functions allow you to create, modify, and extract information about regions of interest (ROIs).

The following table lists the Regions of Interest functions. The functions in the Regions of Interest class are grouped according to the types of operations they perform. The first column contains the name of the class. The second column contains names of function subclasses. The third column contains names of individual function panels. Each Regions of Interest function panel represents one function.
