National Electrical Manufacturers Association Standard PS3: Digital Imaging and Communications in Medicine (DICOM) Part 3.3, 2024b

This 1932-page document specifies the set of information object definitions (IODs) of the DICOM standard. IODs are abstract definitions or data models that represent real-world objects. The DICOM IODs relate to communication of digital images and related medical information. For each IOD, this document specifies:

- any necessary information for the semantic description of the IOD

- relationships to associated real-world objects relevant to the IOD

- attributes that describe the characteristics of the IOD.
