Medical Imaging Resource Center

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

Pointers to files for downloading

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

Display Formats

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, …

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

Author Service connection

The File Service

Demonstration

DICOM Service

Receives DICOM objects from PACS, workstations, modalities, …Automatic document generation

– Images grouped into documents by study– Template-driven– Automatic JPEG generation from DICOM– Programmable anonymization (de-

identification and re-identification)

DICOM Service

Automatic trial patient ID generationConnection to other DICOM Services for clinical trials

– Support for encrypted communications (SSL)

DICOM import / DICOM exportHTTP(S) import / HTTP(S) exportDatabase export

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
