1 Incorporating Radiology Teaching Files and Microsoft ® PowerPoint ® Files into a MIRC System William Weadock, MD Frank Londy Sarah Abate James Ellis, MD Department of Radiology University of Michigan

2 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.

3 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

4 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 –, etc.

5 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

6 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 PCs in reading rooms

7 Disclosure William Weadock, MD Owner, Weadock Software, LLC

8 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, PDFs, etc. –Quality control Simple to search

9 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

10 RadPix and MIRC Meet these Goals

11 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

12 Workflow Example

13 Workflow Animation in Progress STEP 1 Teaching images are exported from PACS Step 1 Exported images

14 STEP 2 Images are opened in RadPix Workflow Animation in Progress Step 2 Images in RadPix

15 STEP 3 – Option A Images can be placed directly into a PowerPoint ® Presentation Step 3a Send to PPT Workflow Animation in Progress

16 STEP 4a – Option A Use Power 2 MIRC to upload text and images to MIRC server Step 4a Power 2 MIRC Workflow Animation in Progress

17 STEP 5 – Option A View on MIRC server Step 5 View on MIRC Workflow Animation in Progress

18 STEP 3b – Option B Export to MIRC server Step 3b Export to MIRC Workflow Animation in Progress

19 STEP 4b – Option B Add information with MIRC Authoring Tool Step 4b MIRC Authoring Tool Workflow Animation in Progress

20 Step 5 View on MIRC STEP 5 View on MIRC server Workflow Animation Complete

21 Two levels of users –Authors Faculty, fellows, residents, others Contribute material –Publishers Approve authors submissions Faculty User Roles - Public

22 Private files only they can access Multiple owners of a document Proxy creators –Secretaries, others can create documents for faculty Document Ownership

23 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:\)

24 Image Routing Abdomen DICOM Image Catcher Neuro Chest

25 Image Routing Result –Bone images -> n:\bone\images –Chest images -> n:\chest\images… Could also be configured as separate system for each radiologist

26 Problems Images collect on server Inadvertent sending of very large data sets – Images –Disk drives fill up! Users must choose representative images

27 MIRC Authoring with RadPix

28 RadPix MIRC support Windows ® -based Loads DICOM images from PC Network

29 RadPix Upload to MIRC

30 MIRC Authoring – Patient Information

31 MIRC Authoring – Case

32 MIRC Authoring – Categories

33 MIRC Authoring - Images

34 MIRC Authoring – Images - Annotate

35 MIRC Authoring - Access Other files, including PDF, TIFF, DOC, XLS, etc. can be included Video Files can be included

36 MIRC Authoring - Access

37 MIRC Authoring - Quiz

38 Sample Case – Annotated Image

39 Sample Case - Quiz

40 Uploading PowerPoint ® files to MIRC with RadPix Power 2 MIRC

41 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.


43 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

44 Sample PowerPoint® Slide Notice the text on slide and in slide notes area Slide notes

45 Example Slide in Power 2 MIRC

46 MIRC Search – TOF

47 MIRC Query Results – TOF 4 Documents found

48 Sample PowerPoint® Slide in MIRC Extracted Notes Extracted Text PowerPoint ® MIRC

49 Extracted Text from Slide Notes

50 Extracted Notes from Slide Notes

51 Current Status of our System CT, US, MRI conferences – –AVIs included PPT files split up - 1 for each case Standardized template for conferences Medical student lectures – upcoming article in Journal of Digital Imaging

52 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)

53 MIRC Admin Hardware Software

54 Michigan MIRC Server - Hardware Dell 2.4 GHz PC 512 Mb RAM (2) 250 Gb disk drives Mirrored RAID Back up system!!!

55 Server Configuration Inside UM firewall Private UM IP subnet ( _._) –Available only inside Institution –Accessible via secure VPN over Internet

56 MIRC Server - Software Windows ® 2000 Server Network Associates VirusScan 7.1 Microsoft ® Security Patches MIRC ( –Sun ® Java –Apache Tomcat

57 RadPix - Software Download trial software from Includes : –RadPix –DICOM client (RSNA SimpleStorage) –RadPix MIRC Authoring Tool –Power 2 MIRC

58 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.
