A Tour of the MIRC Community

Dive into the MIRC community, a global hub supporting the management and sharing of medical imaging resources like teaching files, research images, and clinical data. Learn about its evolution from a central image database to a distributed network of libraries, enhancing accessibility and collaboration. Discover how MIRC functions as a radiological Napster, fostering a unified platform for image searching and sharing across diverse medical imaging libraries.

  1. A Tour of the MIRC Community

  2. The MIRC Objective: Support the production, storage, indexing and distribution of medical imaging resources: • Teaching files • Scientific & technical documentation • Research images & datasets • Clinical trials data

  3. A little history… • MIRC was originally conceived as a large central database of images and related clinical information that would be maintained by the RSNA for open access by the medical imaging community.

  4. Evolution of the concept… • It soon became evident that a more effective strategy would be to leverage existing on-line electronic resources while creating new ones.

  5. The technical approach… • A virtual community • of medical image libraries • with a distributed index • supporting a distributed search mechanism • A kind of radiological Napster • The final result…

  6. An open community of medical imaging libraries and teaching files around the world, cooperating by sharing information through a common query format

  7. Image Searching Prior to MIRC • Use of a search engine or multiple search engines to locate specific images or information. • Alternatively, find a website with multiple links to teaching files.

  8. Image Searching Prior to MIRC • Therefore, somewhat limited with only having the ability to query the single storage repository.

  9. Image Searching Prior to MIRC • Or… • Find another database link via the search engine.

  10. Image Searching with MIRC

  11. MIRC Sites • Query Service • An entry point into the MIRC community for a user on the Internet • Storage Service • A cooperating library • Index: the library’s card catalog • Server: the library’s shelves

  12. MIRC Sites User Query Service MIRC site A Index RSNA site Internet Server Index MIRC site B Index Index Server Server Server MIRC site C

  13. MIRC – a technical definition • MIRC is defined to be a set of servers (query services and storage services) that support: • the MIRCquery and • MIRCqueryresult XML schemas • MIRC places no constraints on how servers display their contents

  14. Query Services • Provide users with query forms. • Translate a query form into a MIRCquery XML object. • Distribute the MIRCquery to all selected Storage Services. • Collate the results and return them to the user.

  15. Standard Query Service • Using the standard query service w/out the case navigator allows you to view the results in a typed page format.

  18. Standard Query Results

  19. Query Services • Selecting the case navigator will take you directly to the first case. The next case will be just a click away.

  21. The Case Navigator Intended for teaching file cases

  22. Storage Services • Respond to queries from Query Services and serve content to users. • Each storage service maintains its own index • Each storage service is responsible for the display format of its content

  27. RSNA Case Display

  28. Complex Query • Can specify a complex search simultaneously across multiple medical image sites

  36. The RSNA MIRC Software • Query Service • Storage Service Storage Service servlet Submit Service servlet Admin Service servlet XML Server servlet • Authoring Tool

  37. The RSNA MIRC Site Software • Serves all kinds of MIRC documents • Runs on all platforms • Personal/departmental teaching file system • Clinical trials support coming soon • Free / open source

  38. The RSNA MIRC Authoring Tool • Creates all kinds of MIRC documents • Runs on all platforms • Submits documents to MIRC sites running the RSNA software • DICOM Store SCP and Q/R SCU • Free / open source
