  1. Medical Image Resource Center

  2. What is MIRC? • “Medical Image Resource Center” • Makes it easier to locate and share electronic medical images and related information • On your PC • In your Department • Throughout the world

  3. MIRC: Why? • MIRC can help: • Teaching and decision support in clinical patient care • Clinical trials • Make research databases more freely available to the imaging community

  4. The Evolution of MIRC • Originally conceived as a large centralized database of images and related clinical information

  5. The Evolution of MIRC • Originally conceived as a large centralized database of images and related clinical information • It soon become clear to us that a more effective strategy would be to: Create a standard that would tie together virtual communities of new and existing medical image libraries

  6. Key MIRC Concepts • Libraries cooperate by supporting a common query mechanism • A Query mechanism allows users to find information within these libraries • MIRC supports multiple information storage formats

  7. Key MIRC Concepts • Libraries cooperate by supporting a common query mechanism • A Query mechanism allows users to find information within these libraries • MIRC supports multiple information storage formats

  8. Key MIRC Concepts • Libraries cooperate by supporting a common query mechanism • A Query mechanism allows users to find information within these libraries • MIRC supports multiple information storage formats

  9. MIRC Libraries • MIRC libraries archive a wide variety of text, images, and other multimedia information • Teaching files • Research and reference image repositories • Collection of disease specific radiographs • Normal variants • Functional brain MR data sets • Clinical trials images and related data • Journal articles • Textbooks • PowerPoint and other types of presentations

  10. MIRC Components • Query Service Entry point into the MIRC community for a user on the Internet, Query service can be created by site using the MIRC query schema.

  11. MIRC Components • Storage Service: Cooperating information library – a web archive or a database, designed to support the MIRC query mechanism. • Index: The library’s card catalog – an XML document that identifies content of a storage service. • Server: The library’s shelves – where the content of a MIRC site is stored or saved.

  12. Index Server Index Server The MIRC Community User • MIRC Query Service: • Access to the community Internet Index MIRC Sites Server • MIRC Storage Service: • - Document Authoring • Document Storage • Document Indexing • Web Server RSNA

  13. MIRC Query Service:User Fills in Query Form

  14. MIRC Query Results:Displays “Hits” from MIRC Sites

  15. MIRC Teaching File Display:MIRC-TF Display Formats

  16. MIRC Authoring Tools New Authoring Tool

  17. MIRC Authoring Tools Image Annotation

  18. MIRC Clinical Trials Features • Image acquisition from modalities and PACS • Image and metadata anonymization • Secure image and metadata transport • Automatic storage and indexing of all data, with the standard MIRC search and display functions • Interfacing to external databases for trial-specific analysis

  19. MIRC Clinical Trial Configuration FC DICOM PI DICOM FC DICOM PI DICOM FC DICOM Modalities Firewalls Workstations Internet HTTP HTTPS • MIRC Site: • Image reception • Image Storage • Transfer to PACS and/or workstations • MIRC FieldCenter Application: • Image reception • Anonymization • Transmission to PI

  20. MIRC in Clinical Trials • MIRC currently only non-proprietary software/standard available free and open source for clinical trials • After extensive evaluation of the software, the National Cancer Institute’s Cancer Imaging Program has selected MIRC’s free and open source clinical trials software suite for use in clinical trials

  21. Other Ongoing Clinical Trials • WHIMS 1-3 (Women's Health Initiative Memory Study) • WHI – Women’s Health Initiative CT Study • CARDIA - Coronary Artery Risk Development in Young Adults • RIDER - Reference Image Database to Evaluate Response to Therapy • CIREN – Crash Injury Research & Engineering Network • Wake Forest (PI) • CAMPS – Carotid Atherosclerosis MRI Progression Study • University of Washington (PI)

  22. Research Dataset Acquisition • MIRC feature developed with Mallinckrodt Institute of Radiology • Allows internal researchers to acquire DICOM images from modalities, store and manage them without using the clinical PACS • Bridges internal networks • Tracks access of PHI for HIPAA compliance

  23. NCI Collaboration • Successful demonstration in early 2005 • Support of current trials (RIDER, LIDC) • Decision to use MIRC for clinical trials in the future • Development of MIRC extensions to support the NCI imaging database

  25. Open Source Project • All source code is available on-line • Zip archive through the RSNA MIRC site • CVS repository • Actively maintained MIRC project list

  26. MIRC User Group Meetings Monday 1:30-3:00 E262 Thursday 12:30-2:30 E257

  27. How to Participate? • Use MIRC to perform searches for images and information • Be an author • Set up a MIRC site: • Connect your existing Teaching File system • Build your own Teaching File system: • Use the RSNA MIRC Site implementation • Use someone else’s • Come up with your own and make it MIRC compatible

  28. Need More Information? • Go to http://mirc.rsna.org • There is a link to “Downloads” where you can find all the documents, software and installation instructions for setting up a MIRC site and creating content.
