Mission

• Step I: Describe and upload retrospective datasets (roughly 1 terabyte) onto the CHB XNAT instance, and confirming that a tractography processing workflow that involves
  • making specific queries,
  • generating and uploading specific results,

is supported by the XNAT API & Data Model.

• Step II: Execute the script-driven tractography workflow

Participants

• sites involved: MGH NMR center, MGH Radiology, CHB Radiology
• number of users: ~10
• PI: Ellen Grant
• staff: Rudolph Pienaar
• clinicians
• IT staff

Data

There are currently about 1540 studies, each with about 1k images

   * Multiple studies
   * Imaging Modalities: MRI
   * Genetic:

Current Workflow

DICOM raw images are produced at radiology PACS at MGH, and are manually pushed to the PACS hosted on KAOS resided at MGH NMR center. The images are processed by a set of PERL scripts to be renamed and re-organized into a file structure where all images for a study are saved into a directory named for the study.

DICOM images are currently viewed with Osiris on Macs.

Data Management need

It is desired to develop an Image Management System for BDC (IMS4BDC) with which at least the following can be done:

• Move images from MGH (KAOS) to a BDC machine at Children’s
• Import legacy data into IMS4BDC from existing file structure and CDs
• Query capabilities: (example) “Show all diffusion studies where patients ages are < 6”
• Mange post-processed images
• Sharing images with clinical physicians; export post-processed data back to clinical PACS
