Optoacoustics (OA) is combined with near‐infrared optical tomography (NIROT) in reflection mode to quantitatively image vasculature oxygen saturation (SO2) levels in phantoms containing vessels at depths up to 25 mm. Using NIROT to estimate the light fluence, the OA signals' spectral distortion was reduced from 60–150% to 10–20%. Results suggest that SO 2 levels can be determined with <10% error and that temporal changes can be monitored with even better accuracy. Further details can be found in the article by Leonie Ulrich, Linda Ahnen, Hidayet Günhan Akarçay, et al. ( e201800112 ).
