Optical and mechanical properties of phantoms. For optical properties of inclusions A–D, values in brackets indicate the contrast relative to the background optical properties: $({\mu }_{\mathrm{a},\text{inclusion}}-{\mu }_{\mathrm{a},\text{background}})/{\mu }_{\mathrm{a},\text{background}}$ and $({\mu }_{\mathrm{s},\text{inclusion}}^{\prime }-{\mu }_{\mathrm{s},\text{background}}^{\prime })/{\mu }_{\mathrm{s},\text{background}}^{\prime }$.
