VOI association can be used in order to establish the default VOIs for images. Select the Dynamic PET in the Series list, and open the association list as illustrated below.
Choose Associate VOI to open a dialog window for selecting a VOI. Preferably it is already available in the database and can simply be selected in the VOLUME OF INTEREST list. Alternatively, Set from File System can be used to point directly to a disk file. Confirm the assignment with Set selected.
The additional VOIs association options available in the selection list are useful for PXMOD batch processing:
To view the association available for a particular image please select select the image in the Series list, and activate the 
button.
In the example above the Dynamic PET is associated to the selected VOI. In order to define its role in a potential PNEURO or PAI processing an appropriate entry can be selected from the Set series TAGGING list, for example CROPPING_BOX.
