Supplement 3D Slicer and Extensible Neuroimaging Archive Toolkit (XNAT) with workflow management system. Provide integration and interoperability between 3D Slicer, XNAT Services and 3-rd party image processing applications and high performance computing systems. Implement it as within currently developed Structural Planning and Implementation in Neurological Exploration (SPINE) System.

Approach, Plan

Our approach for analyzing diffusion tensors is summarized in the Main Project Page reference below.

Our plan for the project week is to present live demo for use case instances, show examples of integration Slicer3, XNAT and Cluster Computing using Service Oriented Architecture (SOA) and Workflow approach. We also planning to quest for demanded by end-users modules that need improvement in Slicer3 (such as Brainmask Extraction), setup automation for upgraded EM Segmentation Module. We will provide on-demand tutorial for composing workflows of Slicer3 modules.


Prior to Project Week: Interaction with XNAT data repository and Cluster Computing had been implemented. Several use cases had been deployed:

  • Emphysema Assessment: Integration of Slicer Extension, Cluster Computing, XNAT Image Repository
  • Image Preprocessing Workflow for EM Segmentation: Integration of Slicer Internal Modules, XNAT Image Repository
  • Registration and Resampling to Common Space of Multi-Modality (PET/CT) Images for Longitudinal Studies: Integration of Slicer CLI and GUI Modules. (See Slicer Wizard for PET/CT workflow for details).
  • Complex Image Processing using Slicer3 and 3-rd Party Modules: Segmentation for Social Cognition Study for MS Patients (PECS University, Hungary File:SlicerWF NAC PECS Workflow.pdf )

During Project Week:

  • Adaptation of updated BRAINSFit module (Slicer 3.7 June builds) to registration pipelines
  • Tuning Workflow for Registration and Resampling to Common Space of Multi-Modality (PET/CT) Images for Longitudinal Studies
  • Training on Java SPECTRE skull stripping / brainmask extraction module (MIPAV version, Slicer CLI Pending release)
  • Training on updated EM Segmenter (Slicer 3.6)
  • Discussion of Grid Wizard (GWE) integration with workflow instances
