Figure 2. LGE and T₁ Map Reconstruction.

3D LGE image is reconstructed by performing a 3D Fast Fourier Transform on the data acquired using the inversion time $T_{\mathit{\text{inv}}}^{\mathit{\text{null}}}$. The three remaining datasets corresponding to $T_{\mathit{\text{inv}}}^{1-3}$ are first reconstructed using compressed sensing reconstruction. Subsequently, these data and the fully-sampled LGE dataset are used for estimating T₁ maps. Finally, the polarity of the LGE data is restored using the T₁ recovery curve information.
