In this work a gradient coil design technique is outlined that uses a numerical wave equation solution methodology along with an optimization technique to obtain the propagating wave fronts through an inhomogeneous porous media, which essentially determines the winding patterns of the different gradient coils in the appropriate coordinate system. It is shown that such an approach is flexible and can be used to design quality gradient coils with large imaging regions. The quality of the gradient coils is measured through a number of key variables, and these are compared to the Siemens Sonata gradient coil set.
