We have studied the dependence of stability of the free induction decay signal on the time of the spin echo and the time of pulse sequence on real tomographic image. The reconstruction of images using direct and inverse Fourier transform has been carried out. We estimated the changing of characteristics of the restored images. The relations between the pulse sequence parameters time of the spin-echo TE and time of the pulse sequence TR have been set. We used a confidence interval for a full assessment of the accuracy of the calculation of the correlation coefficient compared to point evaluation. The creation of optimal conditions for a tomographic experiment, where TE and TR are set, signal stability provided, has been investigated.
