Presentation Transcript

  1. MIRCMedical Imaging Resource Center A Tour of the MIRC Community Rex Jakobovits, PhD Affiliate Professor, University of Washington President, Vivalog Technologies* *Vivalog is a provider of commercial teaching file solutions Slides contributed by John Perry and Rodney Shaffer

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

  3. Approach: • Enable a virtual community • of medical image libraries • with a distributed index • supporting a distributed search mechanism • Peer-to-peer sharing, like Napster

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

  5. Searching Imaging Resources, B.M. (Before MIRC) • Google • Unstructured, free text • No way to specify “give me chest x-rays on male patients with pneumonia” • Hit and miss, inconsistent results • No way to say “just give me teaching files, not random web pages”

  6. Searching Imaging Resources, B.M. (Before MIRC) • Browse isolated collections • No way to query across systems • Need to learn heterogeneous query interfaces • Results not aggregated

  7. Searching Image Resources, A.M. (Age of MIRC) • A unified query interface • Structured querying across multiple repositories • Results aggregated in a case browser • Control over how results are displayed • http://mirc.rsna.org

  8. How does it work? • MIRC committee defined some important standards: • MIRCDocument Schema • MIRCQuery Schema • Each repository can participate as a MIRC Storage Service,responding to queries from any MIRC Query Service

  9. 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

  10. 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

  11. 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.

  12. 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

  22. How can I participate in MIRC? • Create cases using a free web-based MIRC teaching file authoring system • MyPACS.net, Medpix, etc.

  23. Adding Images to a Case

  24. How can I participate in MIRC? • Create cases using a free web-based MIRC teaching file authoring system • Create MircDocuments with the free RSNA MIRCat, and upload them to a MIRC storage provider
