摘要: Magnetic field strength has always been an important parameter to consider for Resonance Imaging (MRI). It is generally agreed that the Signal Noise Ratio (SNR) approximately proportional magnetic [1,2], although other more subtle effects, such as chemical shift dispersion and susceptibility, also scale with can cause problems good anatomical imaging. However, it no surprise learn engineering challenges presented by commercial construction of higher MRI systems are formidable. This chapter opportunity introduce these a wider audience.
