DICOM-Related Application to Security
Screening Equipment
The Department of Homeland Security (DHS) has a
wide array of horizontal modality / workstation and
vertical information science needs remarkably
comparable to medical imaging needs.
To be sure, the DHS requirements have application
specific details that uniquely characterize the various
applications.
Existing systems are proprietary and closed to outside
innovation.
The DHS and its operating divisions – such as the
Transportation Security Administration (TSA) seek
significantly enhanced performance in next
generation systems, through the involvement of 3rd
parties.

• Past and Continuing DHS Efforts have identified the DICOM as
an opportune asset for accelerating achievement of next
generation system goals.
• To illustrate this potential, a DHS B-B Image Analysis DICOM
Adaptation was drafted for the X-Ray CT Based EDS
application.
• This is one step toward achieving an open architecture X-ray CT
that can accept third party image reconstruction and image
analysis algorithms.
• Presently, the DHS CT A-A Image Acquisition DICOM
Adaptation is being drafted. Support from the Medical Imaging
community is sought.
• A second effort has been creation of a high level Common
Standards Requirements Specification.

U.S. NEMA
Digital Communication Security (DICOS)
Industrial Security Imaging and Communications (4IIC) Section and
Technical Committee
The DHS has requested that NEMA present a comprehensive proposal
for developing standards that meet its short (June’09) and longer range
needs. The DHS EDS adaptation has been provided to NEMA to assist
in meeting the June 09 schedule.
The Transportation Security Administration (TSA) will begin acquisition
of approximately 4,000 X-ray CT-based EDS machines beginning in the
2012-2013 timeframe.
These new machines will be replacing existing deployed machines that
are reaching end of their operational lifetime.
Medium and longer range needs are to extend for other security
modalities (based on acquisition needs).

U.S. NEMA
Digital Communication Security (DICOS)
NEMA DICOS work initiate in July’07 and has
produced a multi-modal, DICOM adaptation for the
C-C interface.
Presently the B-B interface work and C-C interface
work are being reconciled.

Medical Imaging Community Support Opportunities
Support can consist of – but not be limited to:
1. Technical commentary upon the B-B interface
DICOM adaptation.
2. Technical commentary upon the A-A interface
DICOM adaptation.
3. Commentary regarding business or financial
models for achieving the CT open architecture,
algorithm interoperability goals.
4. Participation within the U.S. NEMA
Digital Communication Security (DICOS),
Industrial Security Imaging and Communications
(4IIC) Section and Technical Committee.

Concluding Comments
Copies of the B-B interface DICOM
adaptation and the A-A interface DICOM
working draft adaptation is available upon
request.
Copies of the C-C interface work and the
DHS Requirements Document are
available through the NEMA 4IIC POCs.
