(a) Configuration of a source and two detectors for calculating R and ΔΨ in (b)–(e). (b) Calculated results of R and ΔΨ as a function of the target depth and the radius. The background concentration of fluorophore is zero. (c) Calculated R and ΔΨ as a function of the target depth with different background parameters (the target radius is 0.4 cm). (d) Calculated R and ΔΨ as a function of the target radius with different background parameters (the target depth is 1.5 cm). (e) Calculated R as a function of the inclusion depth at different ratios of the target concentration to background.
