Welcome to the MIRC Wiki

1 The MIRC Project

The MIRC project was initiated by the RSNA Radiology Informatics Committee to construct a library of medical information, globally accessible to the imaging community through the Internet. The project 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.

The RSNA manages an open-source project that has produced software making it easy to install a system for teaching files and clinical trials at no cost. Numerous other developers have produced complete or partial MIRC implementations.

2 The MIRC Community

Many MIRC communities have arisen - some within institutions and some shared globally. The RSNA maintains a MIRC site that provides access to libraries around the world.

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.

Authors on a storage service 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.

There are several ways for an individual or an institution to establish a system that can participate in a MIRC community:

  • The RSNA MIRC software provides both a query service and a storage service as well as support for the MIRC-defined authoring format.
  • An existing teaching file system can be modified to use its internal database to provide an index of its documents, requiring only the construction of the software layer necessary to respond to a MIRC query.
  • Some commercial teaching file systems also support the MIRC query mechanism, allowing them to participate in a MIRC community.

3 The Architecture of the RSNA MIRC Implementation

The RSNA MIRC implementation meets all the requirements for participation in a MIRC community. It also includes many other features not required by MIRC but desirable for the integration of MIRC into teaching institutions, institutions participating in clinical trials, etc.

The RSNA MIRC implementation is based on the Apache Tomcat servlet container. A servlet container can be thought of as a web server that knows how to run Java programs called servlets. A group of related servlets is called a webapp. The MIRC implementation includes a number of webapps, generally one for the query service, one for each storage service installed on the server, one for a file service, and one for server-level administration functions.

Further information is included in a separate article.

4 User's Manual

The RSNA MIRC implementation has numerous components for accessing, creating, and managing documents and files. Information on how to use the RSNA MIRC software is collected in a separate article.

5 Administrator's Manual

The RSNA MIRC implementation is designed to require minimum management effort. A separate article describes how to set up a MIRC site using the software and how to configure it to meet the needs of its users.
