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.
