Table 1.

Shown are the means and standard deviations of total errors ∆_ϕ in ms over the whole do main Ω between reference and optimized solutions for varying degrees of noise σ and spatial undersampling ${\hat{\Omega }}_O$. Initial errors of 3F and HPS model were μ _Δ = −1.4ms, σ_Δ = ±11.3ms and μ _Δ = −23.0ms, σ_Δ = ±8.3ms for 3F and HPS model, respectively.
