Objective
We are integrating finite element mesh creation tools developed at the University of Iowa into 3D Slicer. The result will be that 3D Slicer models can be further processed into meshes for analysis using external finite element programs, such as ABAQUS.
Approach, Plan
Standalone mesh creation tools exist in the standalone application IA-FEMesh found by clicking here.
During this week, we will be testing the second iteration of integration with 3D Slicer. This implementation uses MRML display nodes to display the meshes and supports interactive exploration and edting with VTK 3D widgets.
Progress
Software for the fiber tracking and statistical analysis along the tracts has been implemented. The statistical methods for diffusion tensors are implemented as ITK code as part of the DTI Software Infrastructure project. The methods have been validated on a repeated scan of a healthy individual. This work has been published as a conference paper (MICCAI 2005) and a journal version (MEDIA 2006). Our recent IPMI 2007 paper includes a nonparametric regression method for analyzing data along a fiber tract.
