A solid phantom recipe for biophotonics applications: a step towards anatomically correct 3D tissue phantoms

We present a well-tested, broadband (600-1100 nm) characterized phantom recipe to manufacture tissue mimicking optical phantoms over a wider range of optical properties (absorption 0.1-1 cm-1, reduced scattering 5-25 cm-1) relevant to human organs. The results of various tests like linearity, reproducibility, homogeneity showed the phantom recipe is robust with less than 4 % coefficient of variation (CV). Finally, a non-scattering 3D phantom of the infant's torso was presented to project the futuristic aspect of our work that is to 3D print human organs of biomedical relevance.
