“Electronic Health Record”
• Image Management system and Departmental Information Systems
must be EHR-prepared (Query/Retrieve)
• EHR: emphasis today on visual integration on the desktop, will
become the integrated, secure, patient centric, source of health
information
• Need for coded vocabularies to represent medical knowledge and the
patient’s health condition
• Web front-end:
– viewing not only of images but also waveforms, measurements,
reports, lab results, etc
– need the capability to access the original medical images
– support for (DICOM) Structured Reporting
– XML and XML Schema for the exchange of clinical documents

Strategic planning process
• In recent meetings WG10 has identified quite a
number of strategic topics in the following
domains:
–
–
–
–
–
–
data acquisition, imaging technology
post-processing and presentation
object management and archiving
data and result distribution
treatment planning
workflow management

Topics in Acquisition domain:
– Workflow outside the Radiology domain: RT, VL,
Cardio. Requires specialized workflow. Refreshing the
worklist, event based.
– Amount of data generated, kind of data generated.
• More, 3D, real-time, grayscale, color, time-sequence, text
• Text really broadens the scope: evidence documents, key
image note, codes, vocabularies, templates. Need for simple,
small documents, e.g. just a few measurements
• Amount of data will impact performance
• Need to manage separate objects that do belong together, SOP
Class future. modeling instead of SOP ( HL7 way), separate
info model from communication
December5, 2002
IHE @ RSNA 2002
29
Topics in Acquisition/Post-processing domain:
– Integration, data from multiple modalities needed
together, fused, merge recipe. Requires synchronization
in time and/or space.
• US + CathLab
• PET + CT
• MR + NM
– Communication technology
• Media for exchange, profiles
• Wireless (TCP/IP is on top of this, should be no issue)
December5, 2002
IHE @ RSNA 2002
30
Topics in Archive domain:
– Delete service. All images come together in central
archive with satellites. Co-operation in a loosely
connected environment.
– Co-operation between multiple loosely connected
workflow managers.
December5, 2002
IHE @ RSNA 2002
31
Topics in Diagnostic Review domain:
– Presentation, have only grayscale presentation currently.
•
•
•
•
color, 3D, waveform, Cine, MR-multiframe
hanging protocols
multi-modality presentation
SR presentation
– Interactive collaboration, tele-radiology
– Data mining, statistics, need for uniform definition.
• Should we organize a workshop on this topic?
December5, 2002
IHE @ RSNA 2002
32
Topics in Reporting domain:
– Harmonization with CDA L3, XML encoding
– Next versions of TID 2000, templates
– Codes, Vocabulary, Procedure Codes, Diagnostic
Codes, HIPAA induced codes
December5, 2002
IHE @ RSNA 2002
33
Topics in Result Distribution domain:
– DICOM’s document paradigm: Persistent Object
Reference
– Exchange information outside the DICOM domain
– HIPAA, Privacy, Security, Authentication, VPN
– CD/DVD for exchange

Strategic planning process
Summary of the statements made:
–We started with the ultimate goal in mind: Quality of
Patient Care, Continuity of Care, and the two contributing
factors: fast and accurate diagnosis, and most effective
treatment plan
–The key persons to support with information are the
technologist, radiologist/cardiologist, and the referring
clinician.
–Images, waveforms, measurement reports are generated and
need an integrated presention to the key decision makers.
–We see this integration and presentation to the diagnostic
decision maker as the top priority.
December5, 2002
IHE @ RSNA 2002
37
Strategic planning process
Statements (continued):
–We have the feeling that much is available in DICOM
which is not deployed in practice to solve integration and
presentation problems
==> Education and promotion task
–There will be gaps as well.
==> Identify the gaps in the Radiology, Cardiology, NM
and US domain
–Imaging (related) information from other domains
(-ologies) needs to be integrated as well
==> Convince other -ologies to use the DICOM paradigm
for their persistent objects.

When new technology is required, the strategy is to adopt proven
international, industry or de facto standards.

IHE - Integrating the Healthcare Enterprise
Reducing the Barriers to Optimized Patient Care
• Fostering communication between vendors and users of
medical information technology
• Gaining knowledge of the data required for optimal
patient care decisions, i.e. understanding each others
problems
• Driving the deployment and evolution of existing
standards
• Eliminating the gaps and redundancies in data access.
December5, 2002
IHE @ RSNA 2002

Liaison with TC 215
• Good Type A liaison since April 99.
• Procedure
– TC 215 has agreed to rely on DICOM for Medical Imaging
Standardization
– DICOM offers expertise in medical imaging, with world-wide
users and vendors representation.
– Need to ensure coherence with other ISO standards group on
imaging related issues (e.g. ISO JTC1 SC9 on JPEG 2000)
• New workitem: Web Access to DICOM’s Persistent
Objects, co-operation of ISO TC 215/WG2 and DICOM
– in DICOM a WG6 ad-hoc group is established to work on the
supplement, together with a group of ISO nominated experts
December5, 2002
IHE @ RSNA 2002
43
Collaboration with HL7
• WG20: Integration of Imaging and Information Systems,
common DICOM-HL7 working group.
• Works on the harmonization of the information models,
HL7 RIM and DICOM Real-World model.
• Works on the harmonization of DICOM SR and the HL7
CDA (Clinical Document Architecture) level 1,2,3
– An informative annex to the DICOM standard will be created with
the mapping of DICOM header data element to CDA level 1.
– CDA level 2 and 3 are progressing.
