Abstract

High-performance gradient coils are always needed in magnetic resonance imaging (MRI) systems. However, conventional target-field methods for coil design have drawbacks such as extra magnetic deviation caused by a wire connection. In this work, a crescent-shaped structure is proposed to design bi-planar transverse gradient coils for a 50mT MRI system, in which the shape of each loop is determined by only three positional parameters, making it convenient to optimize. Smooth arcs with gradual-changing radii replace the extra connecting lines brought by conventional methods. An optimization problem aiming at high coil efficiency was established, and the optimal design was compared with the calculation result of a conventional target-field method. It is found that the efficiency of X and Y gradient coils is respectively 97.37 μT/m/A and 99.87 μT/m/A, higher than 89.32 μT/m/A and 91.57 μT/m/A of conventional target-field approach. Finally, the optimal gradient coils were constructed, and the effectiveness of the simulation was validated.
