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

Figure 7

Measured SSFP signal (black dots) in a constant gradient field compared with the theoretical predictions assuming a boxcar lineshape (see Equation (32) and blue solid line) and a Lorentzian lineshape (see Equation (26) and red dotted line). This figure shows the need to predict the SSFP signal using the exact form of the lineshape rather than its Lorentzian approximation.
