【Abstract】 In order to achieve a breakthrough in the development of 3.0 T cranial magnetic resonance imaging(MRI), this article analyzed the cranial brain MRI. According to the analysis results, the main magnet coil was optimized, and a mathematical model was established to perform optimized calculations. A physical model was built based on the calculation results and the electromagnetic simulation analysis was conducted. The analytic results show that the uniformity of the magnetic field meets the design requirements. Therefore, the proposed optimized design of the main magnet coil has a higher magnetic field uniformity under the condition of reduced structure.更多还原
