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

Figure 11

Comparison of lineshapes in the static dephasing for the exact dipole field according to Equation (13), the alveolar surface model given in Equation (14), and the extended alveolar surface model given in Equation (15). The lineshapes for the exact dipole field are obtained from Equation (13) for shown as blue solid line and for as red solid line. The lineshapes in the extended alveolar surface model are obtained from Equation (15) for (blue dotted line) and for (red dotted line). The black solid line shows the lineshape in the limit obtained from Equation (14) that corresponds to the alveolar surface model.
