MIRC Medical Imaging Resource Center A Tour of

MIRC Medical Imaging Resource Center • A Tour of the MIRC Community • Rex Jakobovits, Ph. D • 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

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

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

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

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”

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

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

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

MIRC Sites MIRC site A User Query Service Index Server RSNA site 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

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.

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
