Abstract :
The design principles of MRI (magnetic resonance imaging) main magnets and the problems in the design process are analyzed. A computer program in which the critical characteristics of superconductor, the uniformity of the magnetic field, the economization of the magnet, and the selection of magnet constructions are considered has been established. The program can also be used to design high-uniformity superconducting magnets in some other uses. Five different magnet constructions are treated. By analyzing the computer results some conclusions useful for the practical design of the magnets are obtained
