Inter-slice Motion Correction for fMRI

Objective:

   * To perform inter-slice motion correction in fMR images using affine and non-rigid registration methods. 

Progress:

   * Implemented and tested b-Spline registration with Well Mutual Information metric.
   * Working on affine motion correction using MI.
 

To Do:

   * Right now, registration is done on a slice by slice basis. However, due to the low resolution of fMRI and the absence of gradients result in low registration accuracy. We are investigating using alternative image-to-image metrics like the KL divergence. We are also looking at simultaneously registering multiple slices. 

Key Investigators:

   * Firdaus Janoos, Raghu Machiraju, Steve Pieper, Wendy Plesniak.
