CNR and SNR values of the simulated lesion when imaged with the conventional 1D and the 1.5D ARFI array (n = 30). A 2.92 dB average improvement in CNR was achieved with the 1.5D ARFI array (two-sided t-test, p < 0.0001). The average SNR values inside and outside the lesion were also significantly improved with the 1.5D ARFI array (p < 0.0001).
| Transducer | CNR (dB) | SNRlesion (dB) | SNRtissue (dB) |
|---|---|---|---|
| Conventional 1D | 6.91±1.21 | 7.29±0.62 | 14.48±0.97 |
| 1.5D ARFI | 9.82±0.83 | 11.02±0.68 | 23.26±1.64 |
