Eigenspace-based minimum variance adaptive beamformer combined with delay multiply and sum: experimental study [PDF]
BiOS, 2018 Delay and sum (DAS) is the most common beamforming algorithm in linear-array photoacoustic imaging (PAI) as a result of its simple implementation. However, it leads to a low resolution and high sidelobes. Delay multiply and sum (DMAS) was used to address
