Paraview Support for Computational Anatomy

• Implemented in conjunction with proposal 3D Shape Analysis for Computational Anatomy

Key Investigators

• Kitware: Michel Audette, Luis Ibanez, Julien Finet, Andinet Enquobahrie, Stephen Aylward, Will Schroeder
• Johns Hopkins: Michael Bowers, Anthony Kolasny, Michael Miller

Objective

• Enable Paraview to support VTK-based visualization and ITK-based processing for 3D Shape Analysis Computational Anatomy.

Approach, Plan

• Anatomical components to be manipulated as a scene composed of MRML nodes, e.g.: VolumeNode, ModelNode, etc.
• Interaction possible between Slicer and Paraview.

Progress

A new library, KWScene, is being developed based on the MRML standard to support scene graph-type manipulation of volume and surface primitives for VTK-based visualization and ITK-based processing. This library will facilitate Paraview use in the computation pipeline and visualization of Computational Anatomy research at Johns Hopkins Center for Imaging Science. Reading and serialization is compatible with Slicer scenes.

Delivery Mechanism

Summer Project Week will be used to demonstrate to JHU CIS the work done so far at Kitware on KWScene, in relation to the data types and file formats routinely used in their Computational Anatomy research, and to develop a VTK-plugin mechanism for ITK-based processing on Paraview.
