In photoacoustic (PA) imaging using commercial ultrasound transducers, two dimensional PA images are pro-duced by commonly used delay-and-sum (DAS) as the reconstruction method. However, the reconstructed image is a ected by noise and artifacts. Here, we investigate the performance of a nonlinear (N...
