| Abstract(in English) | Diffusion ordered 2D NMR spectroscopy (DOSY) estimates a diffusion coefficient and a spectrum by using nuclear magnetic resonance (NMR) spectroscopy. In order to estimate, some methods, called the conventional method, use an equation of an ideal signal intensity model. However, in actual measurement, the signal intensity model is distorted by an inhomogeneity of magnetic field. Thus, an accuracy of the conventional method is low. In order to solve this problem, this paper proposes a method which uses information of terms of high order degree of the distorted signal intensity model. An advantage of the proposed method is shown in simulations. |
