The DicomDataSets.ReadDirectory method in DicomObjects can be used to read DICOMDIR files. A DICOM directory has a four-tier hierarchy (PATIENT –> STUDY –> SERIES –> IMAGE). The current version was developed by the DICOM Standards Committee. It was first developed by the joint efforts of the American College of Radiology (ACR) and the National Electrical Manufacturers Association (NEMA).
