Table 3 FWHM and PSL for the point at z = 40.0 mm and contrast parameters in the phantom experiment
From: Sidelobe reduction for plane wave compounding with a limited frame number
Beamformer | FWHM (mm) | PSL (dB) | CR (dB) | CNR |
|---|---|---|---|---|
Normal PWC | 0.68 | − 19.46 | 14.20 | 1.64 |
SVD filter | 0.68 | − 24.22 | 15.27 | 1.79 |
Our method | 0.67 | − 27.35 | 16.11 | 1.81 |
