Photoacoustic tomography acquisition for the blood and ink phantoms. a Phantom used for the discrimination study between blood dilutions. The inclusion in gray is China ink, and the two black inclusions are blood at two different dilutions. b Three photoacoustic experimental ROI images after thresholding at different wavelengths. c Spectral profiles of the selected pixels from each inclusion with (upper) and without (lower) normalization
