scope:

The Digital Imaging and Communications in Security (DICOS) Standard, designated as NEMA IIC 1 v02A, provides a data interchange protocol and an interoperable, extensible file format to facilitate data information interchange (e.g., demographic information, x-ray radiographs, CT images, material-specific information, trace detection signatures, threat assessment) of objects of inspection (e.g., checked luggage, carry-on luggage, parcels, and personnel) for security screening applications.

NEMA IIC 1 v02A is inspired by and relies heavily on elements of Digital Imaging and Communications in Medicine (DICOM). NEMA IIC 1 v02A adapts DICOM as necessary for security screening applications. NEMA IIC 1 v02A includes many references to elements in the DICOM Standard. In text, these references take the general form, see DICOM PS X.Y. Other elements of NEMA IIC 1 v02A, while initially inspired by DICOM, were updated for airport security screening applications. NEMA IIC 1 v02A reflects these adaptations.

Note: From this point forward, while NEMA IIC 1 v02A is retained as the formal Standard designation, NEMA IIC 1 v02A is referenced as its informal designation, DICOS v02A.
