2009 Summer Project Week Slicer3 XNAT usecases

Use Case 1: Image Guided Therapy Planning and in OR

Workflow

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 querieswebservices 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).

Use Case 2: Radiation Treatment Planning

Workflow

Step1. Patient is scanned and data is pushed to XNAT (and referenced by a PACS system) automatically.

• possibly DICOM DCMRT metadata automatically applied
• other assessors may be collected and described manually, uploaded to XNAT using client GUI.

Step2. Scientist/Clinician queries for patient data, browses results, downloads to RT planning software

Step3. Scientist/Clinician uploads plan in progress. DICOM DCMRT metadata automatically applied at upload.

Step4. Researcher queries for case data, browses results, downloads to local disk for study.

Specific Metadata Requirements or Data Model modifications

• DCMRT supported by DICOM rule?

Use Case 3: Quality Control Processing of Large Studies

Use Case 4: Longitudinal Studies

Use Case 5: Population Studies
