Signal strength is modified by properties of each proton's microenvironment, such as its mobility and the local homogeneity of the magneticfield.
发射信号的强度由每个氢原子周围的微环境的性质来调整，如质子的移动性与磁场的局部的均一性。

Numerical implementations show that this method provides a main magneticfield with homogeneity and strength at the imaging region, which is defined outside of the magnet structure.
