Experimental performance of WGAN-GP on a hair phantom. (a–c) Results from time-reversal, UNet, and WGAN-GP, respectively. Red arrows denote the stripe artifacts due to limited view. (d and e) Lateral and axial profiles along the dashed red lines in (a). Scale bar: 5 mm. (A color version of this figure is available in the online journal.)
PA: photoacoustic; WGAN-GP: Wasserstein generative adversarial network with gradient penalty.
