The National Electrical Manufacturers Association (NEMA) published NEMA IIC 1 v01 Digital Imaging and Communications in Security (DICOS) Information Object Definitions (IODs).
Known informally as DICOS v01, this new standard specifies an extensible, interoperable data format that enables the integration of security screening technologies across multiple vendor platforms, and facilitates wider participation in the development of improved security screening technologies and algorithms. DICOS v01 specifies the data format for computed tomography (CT) images and x-ray radiographs that result from airport security examination of checked and carry-on baggage.
The standard provides a common format for threat detection reports that capture data resulting from the use of automated threat detection methods to evaluate the data resulting from checked and carry-on baggage security evaluation. DICOS v01 is inspired by, and relies heavily on, elements of Digital Imaging and Communications in Medicine (DICOM), which is used in virtually all hospitals worldwide. DICOS v01 adapts DICOM as necessary to accommodate the unique needs of an airport security screening application.
DICOS v01 was developed by NEMA's Industrial Imaging and Communication Section, in cooperation with the U.S. Department of Homeland Security's Science and Technology Directorate and Transportation Security Administration.
