Shielded Matrix Gradient Coil

A wide variety of imaging strategies relying on nonlinear gradient fields such as parallel image acquisition, reduced field of view acquisition or curved slice imaging have been presented recently. All these techniques require a certain type of nonlinear gradient field. Here we present a design of a shielded matrix gradient coil and show field maps of prototype elements. Greater flexibility of the achievable gradient field shapes might be beneficial for all of the above mentioned methods.
