Lineshape of Magnetic Resonance and its Effects on Free Induction Decay and Steady-State Free Precession Signal Formation

Figure 6

Comparison between Lorentzian lineshape and alveolar surface model. The initial signal is shown in dependence on repetition time and flip angle for a Lorentzian lineshape (a) obtained from Equation (29) with the parameters given in (b). (c, d) The - and -components for the alveolar surface are obtained from Equation (35) for the same parameters.
