Abstract: Accurate parametric models represent an important prior information for analyzing MR-experiments under large deviations (strong signal and spectra distortions). Free Induction Decay (FID) is a fundamental signal detected in Fourier-Transform MRS. This ideal FID-signal is supposed (implicitly or explicitly) in many quantification schemes. However, a very large class of real-world MR-experiments require a generalized FID-signal. A real-time interactive MATLAB-simulator has been developed for modelling the complex inhomogeneity, noise, phase, amplitude, truncation, apodization, and some other distortions involved in the generalized FID-models.
