Figure 5:

Example images selected from the 4D flow data. ReVEAL4D, kt SPARSE-SENSE, and L1-SENSE are compared to fully sampled data. The first row contains the normalized magnitude images. The second row contain the absolute difference in magnitude between the fully sampled data and accelerated images. The third row contains the velocity maps (cm/s). The fourth row displays the absolute difference between the fully sampled velocity maps and reconstructed velocity maps. Images were reconstructed at an acceleration rate R = 20.
