Automatic reconstruction of scalp and cortex
After inhomogeneity correction the scalp and cortex of the subject are automatically segmented. The reconstruction of the scalp surface is done by segmenting the subject's head from the background using a level set algorithm. Optimal results are achieved in an iterative process. Cortex segmentation is based on a white matter classification. The result is carefully smoothed and inflated to generate the cortical surface. This surface can be used as an approximate source space for cortical source imaging.
