Table 3 The CTR and CNR of the pork phantom experiment
| Method | CTR (dB) | CNR (dB) |
|---|---|---|
| Original DAS | − 7.5 | − 13.4 |
| Original MV | − 9.4 | − 11.5 |
| Original ESBMV | − 9.6 | − 11.2 |
| BAWT combined with maximum eigenvalue threshold (without deep learning) | − 17.9 | − 6.0 |
| U-net + ESBMV | − 26.3 | − 3.6 |
| U-net + ESBMV + BAWT | − 27.9 | − 3.3 |
| U-net + ESBMV + BAWT + Eigenvalue threshold (the proposed method) | − 28.8 | − 3.0 |
