Most of gradients coils are cylindrical or planar, but deformed gradients that fit an object shape should have superior performance. A truncated singular value decomposition (SVD) is a design method for arbitrary shaped gradients, but the design process is time-consuming, especially for shielded gradients. Moreover, coil performance, such as coil inductance and power dissipation cannot be optimized. In this study, we proposed a new strategy that combines the SVD method with a meta-heuristic method for automatically optimizing desired performance for shielded gradients.
