In this work, we have studied the influence of DSV size, coil length and radius, relative axial offset position of DSV and target gradient field uniformity over the figure of merit in multi-layer asymmetric transverse gradient coils. A simple linear function that defines the optimal coil length to produce a maximum figure of merit given a DSV size, coil radius, axial offset position and introduced uniformity error is obtained. Applying the method and the linear functions derived, high quality solutions are obtained.
