Abstract
- A five-layer superconducting magnet design for 9.4-T whole-body magnetic resonance imaging using an NbTi wire is presented in this paper. In order to control the peak field within the winding region and reduce the consumption of the high-field NbTi superconducting wire, four different conductors were used in four field grades: 9.6, 8.2, 7.0, and 5.2 T, respectively. The 0–1 integer linear programming optimization method was adopted to obtain the final coils' geometries. The design has an inner diameter of 0.95 m and a length of 2.9 m. The field uniformity is better than 5 ppm over a diameter spherical volume of 30 cm with the maximum magnetic field of 9.57 T in the coil region when the center magnetic induction is 9.4 T.
