MIRC Overview - CTP and TFS
Welcome to the MIRC Wiki
1 The MIRC Project
The MIRC project was initiated to construct a library of medical information, globally accessible to the imaging community through the Internet. The system has evolved to support communities of cooperating libraries, individually managed by healthcare and educational institutions, whose content can be accessed by a user as if it were a single library. The libraries can provide all kinds of digital information, including teaching files, clinical and technical documents, electronic presentations, and imaging datasets for research and clinical trials. Many such communities have arisen - some within institutions and some shared globally. The RSNA maintains a MIRC site that provides access to libraries around the world.
Authors can use a MIRC-defined format to construct teaching files and other documents in a common structure that allows libraries to index the documents in medically meaningful ways. The indexing mechanism provides users great flexibility in searching the MIRC community. Users can perform free-text searches on the contents of documents as well as structured searches on patient criteria (e.g., sex, age), image criteria (e.g., modality, anatomical region, storage format, compression), diagnosis and other codes, through a standard web browser.
Any MIRC site can function as an access point for users, called a query service, or an indexed information library, called a storage service, or both. A query service provides a point of access to a MIRC community. It provides a query form to the user, distributes the search criteria to all selected storage services, collates the responses, and presents them to the user. A storage service responds to the query received from the query service, searches its index for documents meeting the search criteria, and returns abstracts and locations of the matching documents to the query service.
There are many ways to participate in the MIRC community:
- A site can install the RSNA MIRC software. This approach provides both a query service and a storage service as well as support for the MIRC-defined authoring format.
- A site that has an existing teaching file system can use its internal database to provide an index of its documents, requiring only the construction of the software layer necessary to communicate with a query service.
- Some commercial teaching file systems also support the MIRC query mechanism, allowing them to participate in a MIRC community.
