Comments

Internally LEADTOOLS maintains a tree structure, referred to as the IOD Structure, of available Information Object Definitions (IODs). TheseIODs can include default IODs available in DICOM, as well as user defined IODs. You can access any of this information, add to the IOD Structure, or delete items from the IOD Structure using the LDicomIOD class.
