The authors describe a method for the basic and RF field inhomogeneity estimation in NMR based on the measurement of T2 and T*2 .The method combines the gradient and spin echo acquisition techniques to differentiate the T2 and T*2 relaxation times. Exponential approximation of the relaxation process has to be performed. Experimental results for the plastic and copper specimens are shown.
