We present a practical method for designing the transverse and the axial gradient coils for MRI. This method is based on a modification of previous pro-cedures for discretizing the continuous current solution of a gradient coil design. It leads to improved target field quality characteristics as well as other characteristics such as minimization of the energy/inductance, minimization of the residual eddy current effect, minimization of the thrust forces on the coil and cold shields, coil resistance, etc. The new discretization method involves a set of parameters that can be varied to achieve the desired trade-offs of the coil characteristics.
