This paper proposes a method for fully automatic segmentation of brain tissues and MR bias field correction using a digital brain atlas. We have extended the EM segmentation algorithm, including an explicit parametric model of the bias field. The algorithm interleaves classification with parameter estimation, yielding; better results at every iteration. The method can handle multi-channel data, and slice-per-slice constant offsets, and is fully automatic due to the use of a digital brain atlas.
