Fig. 2From: Image improvement in linear-array photoacoustic imaging using high resolution coherence factor weighting techniqueReconstructed images using the simulated data. a DAS, b DAS+CF, c MV, d MV+CF and e DAS+HRCF. A linear-array and point phantom were used for the numerical design. All images are shown with a dynamic range of 60 dB. Noise was added to the detected signals having a SNR of 40 dBBack to article page
