SIRS contrast dependence with phase. (a) Simulated contrast amplitude as a function of \(T_{SL}\) and the initial phase of the target oscillating field \(\varphi\) for a sinusoidal field in resonance with the SL pulse for (i) BASL, (ii) RESL and (iii) CRESL. (b) Measurement and simulation of the contrast in resonance condition as a function of \(T_{SL}\) for the cases of triggered (\(\varphi = 0\), circles and plain lines) and averaged non-triggered signal (random initial phase, triangles, and dashed lines). \(B_{NC}\) = 75 nT, \(\omega_{NC} = \omega_{SL} = 2\pi 90Hz\).
