[Front cover]

The front cover displays current density images of fourth slice in realistic geometry human leg based on annular electrode mode. (a) Direction current density, (b) intensity distribution of (a), (c) direction current density, (d) intensity distribution of (c), (e) direction current density, and (f) intensity distribution of (e). From the paper "A New Electrode Mode for Magnetic Detection Electrical Impedance Tomography: Computer Simulation Study," by G. Li, L. Hao, R. Chen, and L. Lin on page 2548.
