Meeting Minutes

mi2b2 software

• Chris demo'd the Phase 2 software. No change in user interface from Phase 1. Enter patient MRN, search, goes to our DMC4chee instance in the cloud and gets list of images, can click on image and get series list, click on the series and it fetches the images.
• Bill will be installing the software at MGH this afternoon.
• Discussion regarding the programming underlying the demo. Don't have to queue up C-find, they are asynchronous. Only need to queue C-moves which we were going to do anyway. from BIRN CC has been very helpful in working out the details for the programming. Chris has another call with him to follow up on his research on the DMC4chee libraries to see if they were useful. DICOM queries to XNAT? Built XNAT gateway, a service that manages C-move, C-find commands by translating it to XNAT services and then moves the other way. This is required to manage credentials (e.g. user can only access images they have permission to see). Used this for the Radiology Department, in their reading room, has a single gateway. Can set it up so that user's own log on and password is the same as their gateway password. Partners uses Windows Active Directory for managing user login. Authenticate against Active Directory. Could write a plug-in for Osirix. XNAT has this generic gateway solution.

Workflow analysis

• Discussed new revision based on input from last week now has 5 stages: 1. Select site/department; 2. Scout for information available on system using site-specific identifiers; 3. Form a "Study Set" to request; 4. Chose a Transfer destination and request studies; 5. Check transfer status & view transferred images.

• Cynthia and Wendy have generated a list of questions about the specific details that can be learned by the automatic search functions to use in our filters. Jesse points to standard DICOM feature lists. He offered to share screen shots of the "drill down" query terms on his system.
