Fig. 3From: HF-SENSE: an improved partially parallel imaging using a high-pass filterThe flowchart of HF-SENSE. The k-space raw data is high-passed before undersampling and sensitivity estimation. The SENSE reconstructed image is transformed into k-space data, which is filtered with the corresponding inverse high-pass filter. Final image is obtained by applying inverse 2D Fourier transform to this k-space dataBack to article page
