From: HF-SENSE: an improved partially parallel imaging using a high-pass filter
Results of the simulated axial brain dataset. c = 24 and w = 8 were used in the high-pass filter. The acceleration factor was 4. a, b and d the image reconstructed with SSOS, Tikhonov regularized SENSE (λ = 0.01) and HF-SENSE (λ = 0.001). c The absolute error map of (a) and (b). e The absolute error map of (a) and (d). c and e were brightened 10 times for better visualization
