Freedom to Innovate with DICOS

Enabling greater flexibility for operators to innovate with their security countermeasures.

Digital Imaging and Communications in Security (DICOS) 

DICOS is an extensible, interoperable data standard that enables the integration of disparate security screening imaging technologies, images and related data. It allows images from any security X-ray imaging system and data associated with those images to be transmitted on a common network, stored in a DICOS-compliant storage medium and viewed on any DICOS-compliant workstation or other DICOS-compliant device.

The DICOS standard enables third-party providers, as well as current suppliers, greater flexibility and speed because they can be innovative with security products. Likewise, security operators can achieve greater freedom to innovate with their security countermeasures.

Battelle developed DICOS version 1.0. It was adopted by the Association of Electrical Equipment and Medical Imaging Manufacturers (NEMA), the same association that maintains the international Digital Imaging and Communications in Medicine (DICOM) standard. NEMA is the steward of DICOS and will continue to evolve DICOS based on input and guidance from industry suppliers and users. Version v02A has just been completed, and work on version 3.0 will soon begin by the NEMA DICOS Committee. 

DICOS - how it works


Better Understand DICOS

Feature/Capability

Value Proposition

Open architecture, interoperability

Interchangeability of a true plug-and-play environment enables numerous benefits:

  • Reduced prices (system and software) resulting from greater competition
  • Accelerated development cycles resulting from more players/resources
  • Innovation through non-traditional participants (e.g., algorithm developers)

DICOS - open architecture standard

DICOS is derived from DICOM:

  • Proven based on DICOM’s worldwide experience and use over many decades
  • Published and non-proprietary, allowing users to control the standard through a standards development organization (SDO)
  • Strengthened through industry collaboration and NEMA DICOS standards committee
  • Adaptable over time as needs arise and new technologies emerge 

Networked screening systems

Networking interconnects all generators (screening equipment and security data) and users of security information for multiple benefits:

  • Images and other metadata can be viewed at any workstation; all system elements, including PACS, are integrated to maximize interchange and use of screening related information resulting in prompt and appropriate system response
  • Centralized equipment performance data can be analyzed over time to identify systems degradation or potential operational issues

Risk-based security

Risk-based security is greatly enabled/enhanced by DICOS permitting new concepts of operation (CONOPS):

  • Networking allows remote/dynamic data entry (e.g., hand-held tablets) to improve situational understanding and on-the-spot response
  • Real time access to all data improves risk analysis capability and responsiveness to changing security environment
  • Open security architecture allows enhanced security response (e.g., different algorithms linked to different security risks)

Common image and date standard

DICOS record consolidates all relevant passenger security data to improve security enterprise:

  • Centralizes PAX images (baggage, avatars) and associated metadata; other data (e.g., biometrics) can be added
  • NEMA IIC 1 v02A standard provides 232 pages of details of this image/data standard
  • PAX data can be complemented with third party input (e.g., screener response, behavioral officer input, etc.)
  • Data can be stored and retrieved as required from PACS for analysis, investigations, and response

Operational benefits

  • “Performance over time” analysis of equipment optimizes maintenance
  • Real-time monitoring/analysis of screening process increases efficiency
  • Real-time monitoring of screeners improves performance
  • Screening data and metrics collected online improves CONOPS
