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 “Electronic Health Record” IHE @ RSNA 2002

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 Strategic planning process IHE @ RSNA 2002
The (multi-vendor) Integrated Imaging Solution Connection to other Network and/or TeleCardiology Image Archive Image Server Department Info Server CD Exchange Diagnostic Workstation IHE @ RSNA 2002
Quality of Patient Care Effective treatment plan Fast and accurate diagnosis Images Waveforms Measurements Order Report Treatment plan Diagnose Collect and present Reduce Errors Codes and vocabularies Codes and vocabularies Persistent Object Ref Structured Presentation IHE @ RSNA 2002
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 IHE @ RSNA 2002
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) IHE @ RSNA 2002
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. IHE @ RSNA 2002
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? IHE @ RSNA 2002
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 IHE @ RSNA 2002
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 IHE @ RSNA 2002

Topics in Treatment/Treatment planning domain: CAD tools, HPGL standard, templates for implants 3D, image guided surgery, contours, locate images in 3D space multi modality aspect Image fusion IHE @ RSNA 2002
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. Strategic planning process IHE @ RSNA 2002
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.

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 Liaison with TC 215 IHE @ RSNA 2002
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. Collaboration with HL7 IHE @ RSNA 2002
