Medical Imaging Resource Center A Tour of the

Medical Imaging Resource Center A Tour of the MIRC Community

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

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. MIRC

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

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… MIRC

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

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. MIRC

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 MIRC

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

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 MIRC

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. MIRC

Free Text Search for “Hemangioma” Single Query Searches Multiple Sites • • • Interact. Ed 2 matches Med. Pix 13 matches My. Pacs. net 26 matches Indiana U. 6 matches National Neuroscience 1 match Institute Singapore Casimage Teaching File 7 matches Mallinckrodt 6 matches 61 Matches with Early MIRC Sites • Total Query Time: 3. 7 seconds MIRC

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

The Case Navigator Intended for teaching file cases MIRC

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 MIRC
