How to Author MIRC Teaching Files
MIRC Case Studies: Using MIRC for
Education and Research
Web Classroom Sessions
MIRC Objective
Support the production, storage, indexing and
distribution of medical imaging resources:
– Teaching files
– Scientific & technical documentation
– Research images & datasets
– Clinical trials data
MIRC Concepts
The key concepts:
– MIRC is a community of cooperating libraries
on the Internet.
– The libraries cooperate by supporting a
common query mechanism.
– The query mechanism allows users to find
information wherever it is stored.
MIRC Information Formats
Images: DICOM, GIF, JPEG, PNG
Anything that is displayable by a web browser
Hyperlinks to other web content

Known and unknown presentations
Standard Query Results
The Case Navigator
Intended for teaching file cases
Storage Service
Stores and indexes documents
A single MIRC site can have multiple
Storage Services for different purposes
– Teaching files for each department/specialty
– Individual services for each clinical trial
XML Server
Serves documents to users on the web
Transforms XML files to other formats
Multiple display formats (page, tab, mstf)
Exports documents and datasets to users
XML Server
Provides access control for:
– read, update, export
Restricts access for:
– owners, users, roles (user groups), public
Supports private (owner-only) sections of
otherwise public documents
Display Formats
Page
Tab
MSTF
Submit Service
Allows users to upload MIRC documents to
a storage service
– Supports connections from client-side
authoring tools
– Supports uploading documents via a browser
– Accepts uploads in the format exported by
the XML Server
Author Service
Allows users to create MIRC documents
directly on the Storage Service
Supports multiple templates to allow for the
creation of different kinds of documents
Links to the File Service for inserting links to
images and other documents
What goes in a teaching file case?
Whatever you want:
History
Differential Diagnosis
Findings
Discussion
Diagnosis
Quizzes
References
Images, drawings, videos, audios, …
Admin Service
Allows administrators to manage a Storage
Service through a browser
– Control the documents on the Storage Service
– Adjudicate the input queue for non-publishers
– Configure the Storage Service and DICOM
Service
– Control and monitor the DICOM Service
– Manage users and roles
File Service
Each authenticated user has a private file
cabinet for storage of files of any kind
One public file cabinet for the site
Public file cabinet receives DICOM objects
from PACS, modalities, workstations
– Separate anonymizer

Automatic document generation
– Images grouped into documents by study
– Template-driven
– Automatic JPEG generation from DICOM
– Programmable anonymization (deidentification and re-identification)
DICOM Service
Automatic trial patient ID generation
Connection to other DICOM Services for
clinical trials
– Support for encrypted communications (SSL)

Database Interface
Links to an externally developed database
Provides classes for interrogating:
– DICOM objects
– Metadata files:
• XML
• ZIP (with manifest)

MIRC FieldCenter Application:
- Image reception
- Anonymization
- Transmission to PI
MIRC Site:
- Image reception
- Image Storage
- Transfer to PACS
and/or workstations
Lessons from Field Centers
IT departments are overworked.
Network configuration can be a problem.
– Firewalls, proxy servers, VPNs
Running a MIRC site at a Field Center just
for image acquisition is overkill.
Therefore…
The FieldCenter Application
Runs at the image acquisition site
Receives images and metadata files via the
DICOM and HTTP(S) protocols
Anonymizes images and metadata files
Transmits to the PI MIRC site via HTTP(S)
Automatically links to the PI MIRC site for
remapping tables and software updates
Anonymization
Removal of Protected Health Information (PHI)
Remapping of PHI to trial-specific identifiers
Central vs. distributed remapping tables are an
issue in a multi-site trial
Metadata anonymization may also be required
in some trials
