Design and Analysis of Magnetizing Coil for Magnetic Resonance Imaging Systems. Hollow Cylindrical Coil Design

A typical medical Magnetic Resonance Imaging (MRI) contains a large electromagnet capable of creating a static magnetic field in the range of 0.5 Tesla (T) to 3.0 T with a uniformity across the tunnel of 0.5 parts per million (ppm). The central volume, in which patients are placed, is called the tunnel. The main purpose of this work is to design a thick solenoid coil for MRI scanner. Two key factors in this design are field homogeneity and minimum wired volume consumption. In terms of field homogeneity, I must apply multi constrains, one is considering of superconducting features; another is to apply discretizing and cancelling methods. Here, researches is focused on second key factor (namely optimum wired volume). The procedure which is proposed in this paper is simulated by MATLAB and MAXWELL 16.0 software which can be used in wide variety of solenoid coil design industry, in the range from micro to macro dimension. For example in macro rang, there is an electrical machine in electrical power systems that named superconductor magnetic energy storage (SMES), this generates strength field (i.e. a 5 Tesla). And in micro rang we can mention miniature medical diagnostic coils.
