Study on Influence Factors of NMR T2 Spectrum Inversion

It is essential to investigate influence factors of inversion for improving inversion quality. Firstly to classify the influencing factors, then to make numerical experiment for each influence factor using the forward and inversion simulation technology. The results show that the collection parameters and quality of echoes have the great influence on the inversion quality, and the assigned parameters of T2 spectrum inversion have little influence. Hence, optimizing the parameter of echo collection can improve the T2 spectrum inversion quality and application effect of NMR. As for the assigned parameters, they could be selected flexibly according to the concrete conditions.
