Corrections to “An FDTD Model for Calculation of Gradient-Induced Eddy Currents in MRI System” [Sep 04 1983-1989]

In the above titled paper (ibid., vol. 14, no. 3, pp. 1983-1989, Sep. 04), there is an important error in the 3-D finite-difference time domain (FDTD) update equations (1c)-(1e) of the electric field components in the cylindrical coordinates. The corrected versions are presented here.
