Fully Automated White Matter Hyperintensity Lesion Mapping using FSL
We have developed a lesion mapper script using FSL that can measure and label lesion volumes automatically

GPU accelerated MRI reconstruction including magnetic field inhomogeneity, non-Cartesian trajectories, parallel imaging, and image regularization
We have developed code called the “Illinois Massively Parallel Acceleration Toolkit for Image reconstruction with ENhanced Throughput in MRI (IMPATIENT MRI). This toolkit accomodates non-Cartesian trajectories, parallel imaging, field inhomogeneity, and various regularization penalties. All while it speeds reconstruction time up to a factor of 100 or more compared to accelerated CPU code.

Human Physiology Systems Simulation Models
With support from Mathworks, we adapted several human physiology simulation models to enable better visualization of the simulation. There are modules on neurophysiology, cardiovascular physiology, muscle, and endocrinology. The visual representation of differential equations in Simulink allows student to visualize the overall system function, while maintaining the mathematical and quantitative nature of the model. Work is available as courseware through the Classroom Resources site of Mathworks or at the link below
