Image improvement in linear-array photoacoustic imaging using high resolution coherence factor weighting technique
Abstract Background In Photoacoustic imaging (PAI), the most prevalent beamforming algorithm is delay-and-sum (DAS) due to its simple implementation. However, it results in a low quality image affected by the high level of sidelobes. Coherence factor (CF) can be used to address the sidelobes in the...
