Fig. 5
a A reconstructed single wavelength MSOT image of mouse M1 (example of a PDA-KPC tumour) at 800Â nm. The dashed yellow line indicates the tumour. b The corresponding spectrally unmixed image, showing the distribution of Hb and HbO2 components in blue and red respectively. c The oxymap image, showing the distribution of the SaO2 values. The yellow scale bar at the lower-left in each of these images is 5Â mm. The yellow arrows in images b and c indicates the centre of a region that lacks any spectral signature of blood. The background, Hb, HbO2 and oxymap colour bars reflect the magnitude of the photoacoustic signals, deoxy-haemoglobin, oxy-haemoglobin and SaO2, respectively, as calculated by the MSOT system. (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.) (Used with permission.
