Objective
The Intelligent Systems of Medicine Laboratory (ISML) mission is to work towards improving clinical outcomes through appropriate use of technology. We are interested in biomechanics (both engineering biomechanics and sport biomechanics), biomedical engineering, computer integrated surgery, medical robotics and related fields. We run exciting research projects in these areas, generously funded by The Australian Research Council and other agencies (including NIH).
Detailed information about the ISML can be found here [1]
Approach, Plan
We intend to contribute to Na-MIC by providing algorithms for computing the intra-operative brain deformations for image-guided neurosurgery. We treat the brain shift as a continuum mechanics problem involving finite deformations and solve it using non-linear finite element procedures. We use procedures (non-linear explicit dynamics with Total Lagrangian formulation) that do not require solving large systems of equations and are therefore amenable to computing the intra-operative brain deformations in real time (under 150 s) on a standard PC. See also [2]
Progress
The algorithms are already implemented in C/C++ using Visual Studio and MFC. Matlab is used for visualizing the results.
At the Project Week
- Learned from Jim Miller about possible solutions for linking our Finite Element (FE) solver for computing soft organ deformations with Slicer. No decision regarding selection of such solution has been made.
- Talked with other groups (from the College of William & Mary, Laboratory of Neuro Imaging at UCLA, and the University of Iowa) about applying the FE analysis in computing soft organ deformations for image registration.
- Learned from Vincent Magnotta about the hexahedral mesh generator developed at the University of Iowa.
- Attended the ITK and Non-rigid Registration topic break-outs.
