Abstract
A simple design process for the design of elliptical cross-section, tr ansverse gradient coils for use in magnetic resonance imaging (MRI) is presented. This process is based on a flexible stochastic optimizatio n method and results in designs of high linearity and efficiency with low switching times. A design study of a shielded, transverse asymmetr ic elliptical coil set for use in neural imaging is presented and incl udes the minimization of the torques experienced by the gradient set.
