Segmentation can be used to define a part of a volume data set as a 'Region of Interest' (ROI). Such a ROI may consist of one joint region or several unconnected regions. ROIs can be manipulated, for example, by creating intersections or combinations of several ROIs. ROIs are used for the purpose of separating a volume data sets into individual parts and allow analyses to be restricted to specific areas of a data set.
ROIs can also be used to achieve perfect alignment of data sets with each other or with a CAD model. 

All analysis modules of VGStudio MAX support the ROI concept to allow analyses to be performed with maximum performance and validity.
