  1. IHE TCE-based Teaching File Solution Linked with an Open Source e-Learning Platform MILDENBERGER P, AHLERS C, KLOS G, WUNDER K, SCHNEIDER J, DÜBER C presented by Ahlers C

  2. Situation Klinik und Poliklinik für Diagnostische und Interventionelle Radiologie • Conventional film archives obsolete • Digital content resource for teaching and education in Radiology needed • Electronic systems for storage, retrieving, viewing of radiological images and teaching files are available • Existing e-learning platform has limited capabilities for display and organization of radiological images and cases • No interoperability between clinical workspace and e-learning platform

  3. Purpose of this project Klinik und Poliklinik für Diagnostische und Interventionelle Radiologie • Step 1: Integration of clinical workspace with teaching file database to facilitate creation of e-learning content. • Step 2: Integration of teaching files with e-learning platform to merge synergistic functionality. • Assessment and evaluation of the integrated web application

  4. Methods PACS-MIRC integration Implementation of the IHE TCE integration profile (Teaching file and clinical trial export): „Export Selector – A system that allows a user to select one or more instances, series or studies for export… „ TCE Selector: • Image display and selection in PACS client • DICOM send to TCE Selector • GUI to enter keywords and information • Anonymize / pseudonymize • Processing of DICOM instances and content • Generate additional teaching file information (ATFI) and TCE manifests • Send teaching cases with DICOM instances, TCE manifests and ATFI to MIRC for automated generation of teaching files Klinik und Poliklinik für Diagnostische und Interventionelle Radiologie

  5. Methods • Implementation of RadLex categorization system • RSNA project since 2003 • Based on established systems like: ACR Index, SNOMED, UMLS, Fleischner Society Glossaries, DICOM. • All aspects of diagnostic imaging represented:modalities, technique, imaging features, anatomy, pathology. • http://radlex.org Klinik und Poliklinik für Diagnostische und Interventionelle Radiologie

  6. Methods • RadLex is still work in progress and currently not featuring all relevant aspects for breast imaging • Dedicated Mamma TCE Selector. • Implementation of breast specific indexing system • Entity (Berg, Birdwell). • Imaging findings • Anatomy • Postoperative changes • Histopathology • BIRADS • Technical aspects Klinik und Poliklinik für Diagnostische und Interventionelle Radiologie

  26. Klinik und Poliklinik für Diagnostische und Interventionelle Radiologie Results PACS-MIRC TCE Selector – integration of PACS and MIRC Compliant with IHE TCE profile Compatible/adaptable to different teaching file systems Vendor independent integration with any PACS viewer Implementation of a widely accepted categorization system Dedicated version for breast cases Open source Robust, simple, easy to use, set up and configure

  27. Klinik und Poliklinik für Diagnostische und Interventionelle Radiologie Results private MIRC Over 500 teaching files on the “private” internal MIRC server Created within few month parallel to clinical routine, number increasing daily Additional time consumption of about 5 minutes per case High user acceptance for personal study, research and teaching purposes

  28. Klinik und Poliklinik für Diagnostische und Interventionelle Radiologie Results public MIRC Nearly 100 teaching files on the “public” MIRC server for internet access All cases peer reviewed to assure quality of content and complete anonymization Enhanced security using independent “dual server architecture“ Rights management: free to use under creative commons licence, no user accounts for learners

  29. Klinik und Poliklinik für Diagnostische und Interventionelle Radiologie Results MIRC-ILIAS Integration brings together synergistic functionality: ILIAS as university wide e-learning platform used to Provide educational infrastructure Create superordinate learning concept MIRC used for access to image content easy and convenient for authors to create content Improved display and viewing functions compared to generic ILIAS (e.g. Tab file format, DICOM viewer)‏ Direct access to the public MIRC server for self study Easy access to image content within lectures or e-exams

  31. Assessment and Evaluation Klinik und Poliklinik für Diagnostische und Interventionelle Radiologie

  32. Klinik und Poliklinik für Diagnostische und Interventionelle Radiologie Conclusion TCE Selector provides vendor independent integration of PACS and MIRC according to IHE TCE. Integration of MIRC and ILIAS combines synergistic functionality for organization, infrastructure and image display Proved high user acceptance Further potential for development, e.g. supraregional case collection and e-learning platform, worldwide MIRC community
