摘要
该文采用计算机辅助设计的方法,设计了核磁共振成像仪(NMR-CT)中的磁体装置,并建造了模拟磁体装置.理论计算和实际测量的误差只有5.7%,并达到了2088×10^(-6)左右的磁场均匀度.
The magnetic device is the key part of the nuclear magnetic resonance imaging instrument (NMR-CT). We designed this device by computer aided design and then constructed the imitative device. Experiments show that the difference between the calculation and measurement is only 5.1%, and the field homogeneity is about 2088 × 10-6.
