Figure 4

Representative (A) attenuation and (B) emission projections of the gelatin phantom taken during the data acquisition process with a DS Red filter set. The ink doped center of the phantom is dark in (A) as well as noticeable edge artifacts at the phantom’s boundary. Only the ink doped core is visible in the emission projection. The edges of the core appear more intense due to the attenuation of the excitation light as it travels from the edges to the center. The majority of the fluorophores present appear toward the top of the phantom due to imperfect mixing and the non-uniform light source.
