William Weadock, MD Frank Londy Sarah Abate James Ellis, MD Incorporating Radiology Teaching Files and Microsoft® PowerPoint® Files into a MIRC System 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 Disclosure William Weadock, MD Owner, Weadock Software, LLC http://www.RadPix.com 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 in Progress Step 1 Exported images STEP 1 Teaching images are exported from PACS Workflow Animation in Progress Step 2 Images in RadPix STEP 2 Images are opened in RadPix Workflow Animation in Progress Step 3a Send to PPT STEP 3 – Option A ® Images can be placed directly into a PowerPoint Presentation Workflow Animation in Progress Step 4a Power 2 MIRC STEP 4a – Option A Use Power 2 MIRC to upload text and images to MIRC server Workflow Animation in Progress Step 5 View on MIRC STEP 5 – Option A View on MIRC server Workflow Animation in Progress Step 3b Export to MIRC STEP 3b – Option B Export to MIRC server Workflow Animation in Progress Step 4b MIRC Authoring Tool STEP 4b – Option B Add information with MIRC Authoring Tool Complete Workflow Animation in Progress Step 5 View on MIRC STEP 5 View on MIRC server User Roles - Public • Two levels of users – Authors •Faculty, fellows, residents, others •Contribute material – Publishers •Approve authors’ submissions •Faculty Document Ownership • Private files only they can access • Multiple owners of a document • Proxy creators – Secretaries, others can create documents for faculty 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 DICOM Image Catcher Abdomen Neuro Chest 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 MIRC Authoring – Case MIRC Authoring – Categories MIRC Authoring - Images MIRC Authoring – Images - Annotate MIRC Authoring - Access Video Files can be included Other files, including PDF, TIFF, DOC, XLS, etc. can be included MIRC Authoring - Access MIRC Authoring - Quiz Sample Case – Annotated Image Sample Case - Quiz 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 Sample PowerPoint® Slide Notice the text on slide and in slide notes area Slide notes Example Slide in Power 2 MIRC MIRC Search – “TOF” MIRC Query Results – “TOF” 4 Documents found Sample PowerPoint® Slide in MIRC PowerPoint® Extracted Text Extracted Notes MIRC Extracted Text from Slide Notes Extracted Notes from Slide Notes Current Status of our System • CT, US, MRI conferences – 2000-2004 – AVI’s included • PPT files split up - 1 for each case • Standardized template for conferences • Medical student lectures – upcoming article in Journal of Digital Imaging Future • Local PC / Laptop support – Extract certain cases to local PC • Search Local PC • External UM MIRC site? • RSNA Radlex – Replacement for ACR coding • Access from outside world via Internet – Virtual Private Network (VPN) MIRC Admin Hardware Software Michigan MIRC Server - Hardware • Dell 2.4 GHz PC • 512 Mb RAM • (2) 250 Gb disk drives • Mirrored RAID •Back up system!!! Server Configuration • Inside UM firewall • Private UM IP subnet (172.20._._) – Available only inside Institution – Accessible via secure VPN over Internet MIRC Server - Software • Windows® 2000 Server • Network Associates VirusScan 7.1 • Microsoft® Security Patches • MIRC (http://mirc.rsna.org/mirc/query) – Sun® Java 1.4.2 – Apache Tomcat 4.1.29 RadPix - Software • Download trial software from • http://www.radpix.com • Includes : – RadPix – DICOM client (RSNA SimpleStorage) – RadPix MIRC Authoring Tool – Power 2 MIRC Conclusions • MIRC is becoming an integral component of University of Michigan web-based teaching file system. • RadPix and Power 2 MIRC are used as authoring tools. • PowerPoint® presentations and case files can be uploaded to MIRC system. • Content may be either public or private.
