In photoacoustic imaging (PA), delay-and-sum (DAS) algorithm is the most commonly used beamformer. However, it leads to a low resolution and high level of sidelobes. Delay-multiply-and sum (DMAS) was introduced to provide lower sidelobes compared to DAS. In this paper, to improve the resolution and...
