FIG. 1.
High-pass filtering and phase mask multiplication, axial slice through medial femoral condyle of a 3-week-old piglet, data from 9.4 T. First row: homodyne-filtered phase data with different sizes of k-space center used for the process. The other rows demonstrate the appearance of the processed data after different number of multiplications of the phase mask to the magnitude data for each different high-pass filtering.
