From: HF-SENSE: an improved partially parallel imaging using a high-pass filter
Results of the sagittal brain dataset. The Acceleration factor was 4. c = 24 and w = 12 were used in the high-pass filter. a, b and d the image reconstructed with SSOS, Tikhonov regularized SENSE (λ = 0.01) and HF-SENSE (λ = 0.01), the small figures in the right bottom corner of each figure depict the corresponding zoomed in region defined by the white box. c The absolute error map of (a) and (b). e The absolute error map of (a) and (d). c and e were brightened 4 times for better visibility
