XNAT IGTUseCase.png

Step1. Subject is scanned and data is pushed to a networked disk (and referenced by a PACS system) automatically.

Step2. Researcher1 uses an XND client (on a laptop or a desktop system) to

  • apply metadata (DICOM rule sufficient?)
  • upload data to XNAT repository

Step3. Researcher2 opens slicer and queries XND webservices on svr = http://xnd.bwh.harvard.edu:8081 for a list of subjects.

  • Query for all subjects on system
  • Choose a subject, query for available data...
  • Browse results
  • download data of interest

Step4. Completed neurosurgical planning analysis

  • apply metadata (need custom metadata) --must be quick/easy to do
  • and upload results -- must be quick/easy to do (drag/drop, with confirmation0).

Step5. In IGT, search for and download scene for patient (subject)

Clinician cuts network link to remote repository (all files are locally cached so OR system is self sufficient).
