The Objective:The Objective:
Support the production, storage, indexing and distribution of medical imaging resources:– Teaching files
– Scientific & technical documentation
– Research images & datasets
– Clinical trials data
![Page 3: MIRC Medical Imaging Resource Center A Tour of the MIRC Community Rex Jakobovits, PhD Affiliate Professor, University of Washington President, Vivalog](https://reader034.vdocuments.site/reader034/viewer/2022051613/5514919b550346b2598b535a/html5/thumbnails/3.jpg)
Approach:Approach:
• Enable a virtual community– of medical image libraries – with a distributed index– supporting a distributed search
mechanism
• Peer-to-peer sharing, like Napster
![Page 4: MIRC Medical Imaging Resource Center A Tour of the MIRC Community Rex Jakobovits, PhD Affiliate Professor, University of Washington President, Vivalog](https://reader034.vdocuments.site/reader034/viewer/2022051613/5514919b550346b2598b535a/html5/thumbnails/4.jpg)
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,Searching Imaging Resources, B.M. (Before MIRC) 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”

• Browse isolated collections– No way to query across systems
– Need to learn heterogeneous query interfaces
– Results not aggregated

• A unified query interface– Structured querying across
multiple repositories
– Results aggregated in a case browser
– Control over how results are displayed

How does it work?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 – a technical definitionMIRC – 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
![Page 20: MIRC Medical Imaging Resource Center A Tour of the MIRC Community Rex Jakobovits, PhD Affiliate Professor, University of Washington President, Vivalog](https://reader034.vdocuments.site/reader034/viewer/2022051613/5514919b550346b2598b535a/html5/thumbnails/20.jpg)
Query ServicesQuery 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.
![Page 21: MIRC Medical Imaging Resource Center A Tour of the MIRC Community Rex Jakobovits, PhD Affiliate Professor, University of Washington President, Vivalog](https://reader034.vdocuments.site/reader034/viewer/2022051613/5514919b550346b2598b535a/html5/thumbnails/21.jpg)
Storage ServicesStorage 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
