Originální abstrakt

This paper describes a method for the basic and RF field inhomogeneity estimation in NMR based on the measurement of T2 and T2*. In this paper a copper and plastic specimens is used in the Exponential approximation of the relaxation process. To distinguish the value of T2 and T2* relaxation times, we used the method both the gradient and spin echo acquisition techniques. A map of the spatial distribution of the B1 field is used to correct the inhomogeneity, and the quality of the B0 inhomogeneity strongly depends on successful approximation of T2. In this article the method of B1 estimation from the relaxation times via the magnetization transfer ratio is described.
