In the present research we describe the relationship between the figure of merit and target torque minimization value for multi-layer asymmetric transverse gradient coils taking into account the real field profile of long and short bore symmetric and asymmetric magnets. Two torque/force minimization strategies are introduced in order to obtain asymmetric transverse gradient coils with a high minimum torque-maximum figure of merit trade-off. Simple current pattern, minimum torque, high performance head asymmetric gradient coils are obtained combining the real external magnetic field effects over the gradient coil with a specific axial position of the gradient coils DSV.
