[0002] Magnetic resonance imaging (MRI) is a new medical imaging technology that utilizes the principles of nuclear magnetic resonance. The magnet is a crucial component of an MRI system. Magnetic shielding is often used to mitigate the effects of the magnetic field on the environment. MRI coil bobbins typically require excellent magnetic shielding performance.

[0003] In related technologies, the superconducting coils in MRI equipment must operate stably in strong magnetic fields, placing extremely high demands on the coil bobbin's mechanical strength, radiation resistance, and surface finish.
