Frequency Domain Compressive Sampling for Ultrasound Imaging

Figure 12

CS reconstruction on a US image of the skin (a) using a two-dimensional random sampling pattern Φ₁ (b) and two alternative sampling masks Φ₂ (c) and Φ₃ (d) and 33% of samples. The B-mode images of the samples are shown on the second row from (b) to (d). The B-mode images of the CS-reconstructed k-spaces with the optimal 𝜆 are shown on the third rows (e) to (g). Those from the CS-reconstructed k-spaces using the reweighted ℓ₁ minimization are on the fourth row: (h) to (j).
