核磁共振成像用磁体的计算机辅助设计
A Computer-aid Design of NMR Imaging Magnet System
【摘要】 核磁共振成像用的磁体要求在一定的磁场强度下保持大范围的均匀度.本文给出球形空芯磁体和环形空芯磁体的计算机辅助设计方法.
【Abstract】 In NMR imaging, the magnetic field strength is less than 1 Tesla, stability ca. 10-7, and homogenity less than 10-6 in more than 1,000cm3. This can be provided by a spherical or a ring solenoid system A ccomputer-aid design of these two systems in optimization method is also given.
