Fig. 7.

Fluorescence intensity in each well of the optical properties area of the phantom. With 5-nM Qdots, the Maestro and EagleRay-V3 systems exhibit similar intensity trends with different amounts of absorption (hemin) and scattering (${\mathrm{TiO}}_2$) materials. With the Odyssey system, more scattering results in increased fluorescence intensity with a fixed amount of the absorber material. The diffusive edge and scattering effect can be seen between wells from the Maestro image as compared to the sharp edge and low scattering of the Odyssey image, as indicated by the black arrows.
