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

A little history…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 Evolution of the concept…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 The technical approach…approach…•A virtual community

– of medical image libraries – with a distributed index– supporting a distributed

search mechanism•A kind of radiological

•The final result…

MIRC

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

Image Searching Image Searching Prior to MIRCPrior 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 – a technical MIRC – a technical definitiondefinition•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 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.
