摘要
The inclusion of a spatial prior in the high-frequency regime of the scattering transform for the 2-D D-bar method for electrical impedance tomography is studied for use with human subject data. The effects and balance of the two regularization parameters for the inverse problem are studied. Results on data from human volunteers reveal improved spatial resolution when compared to inspiratory and expiratory CT scans.
