Measurement of Inhomogeneity in the B0 and B1 Fields Performed via the Spin-Echo and Gradient-Echo MR Imaging Techniques

摘要：

　　The authors describe a method for the basic and RF field inhomogeneity estimation in NMR based on the measurement of T2 and T2*.The method combines the gradient and spin echo acquisition techniques to differentiate the T2 and T2* relaxation times.Exponential approximation of the relaxation process has to be performed.Experimental results for the plastic and copper specimens are shown.
