Incorporating Radiology Teaching Files and
Microsoft® PowerPoint® Files into a MIRC System
William Weadock, MDFrank LondySarah AbateJames Ellis, MD
Department of Radiology
University of Michigan
Introduction - MIRC
• Web-based teaching file system
• Upload images and text
• Search for text with web browser
– Free text search
– Database field
• Free software created and supported by RSNA.
MIRC Basic Concepts
• 3 Main Components
– Storage
– Query
– Case creation
•Web-based authoring tool
•Web-based editor
– Our institution uses RadPix as the authoring tool
Why do we use MIRC?
• Created and supported by RSNA
• John Perry very responsive to questions and suggestions
• Ability to create / edit / export cases
• Well documented
• Emerging standard for teaching files
• Integrates with other systems
– MyPACS.net, etc.
Why do we use RadPix?
• PC program
– DICOM client to receive images
– Cropping, annotating, window / leveling
– Slide creation
• MIRC database fields
– History, Diagnosis, Pathology, etc.
• Upload completed PowerPoint presentations
• Search for text in presentations
Why do we use RadPix?
• Supports our library of collected DICOM images
• Since 1997
• Logical and flexible workflow
• Does not require Java installation
– Locked down PC’s in reading rooms

Goals of Teaching File System
• Public area – accessible to the department
• Private area - accessible only to the individual
• Content
– Images and text
– PowerPoint® Files
– Movies, animations, PDF’s, etc.
– Quality control
• Simple to search
Teaching File System Requirements
• Easy to Install
• Easy to Use
• Retain High Quality Images
• Add Textual Material
• Edit Cases
• Output Cases
• Simple PowerPoint® Slide Creation
• HIPAA
RadPix and MIRC Meet these Goals
RadPix / MIRC Workflow
• Review case on PACS
• Send individual images to RadPix DICOM client from PACS
• Load images into RadPix
• Enter textual data for case
• Upload case to MIRC from RadPix
Workflow Example

Workflow Animation Complete
• Two levels of users
–Authors•Faculty, fellows, residents, others
•Contribute material
–Publishers•Approve authors’ submissions
•Faculty
User Roles - Public
• Private files only they can access
• Multiple owners of a document
• Proxy creators
–Secretaries, others can create documents for faculty
Document Ownership
Michigan PACS Configuration
• Separate DICOM client for each division
– NeuroPC, BonePC, ChestPC, etc.
• Single PC with multiple DICOM clients receives all images– Same IP address– Different AETitle– Different port
• Workstations configured to send images
• All images routed to department-wide Novell network (n:\)
Image Routing
AbdomenAbdomen
DICOM Image
Catcher
NeuroNeuro ChestChest
Image Routing
• Result
–Bone images -> n:\bone\images
–Chest images -> n:\chest\images…
• Could also be configured as separate system for each radiologist
Problems
• Images collect on server
• Inadvertent sending of very large data sets
– 1000 + Images
– Disk drives fill up!
• Users must choose representative images
MIRC Authoring with RadPix
RadPix• MIRC support
• Windows®-based
• Loads DICOM images from PC Network
RadPix
Upload to MIRC
MIRC Authoring – Patient Information

Uploading PowerPoint® files to MIRC with
RadPix Power 2 MIRC
Power 2 MIRC Features
• Extracts text from PowerPoint® files– Includes titles, text boxes, notes
• Splits PowerPoint® files– For example, if there are 15
different cases in a presentation, they can each be uploaded separately into MIRC
• MIRC data fields– History, findings, pathology, etc.
Power 2 MIRC Features
• Creates MIRC-compatible file
• Uploads to MIRC server
– Includes:•Snapshot image of slide•Text & notes from presentation•AVI video files•Other embedded files•Original PPT file
