Abstract :
Herein we present a comparison of Monte Carlo, radiative transport (RT), and diffusion based forward models for implementation into small animal optical tomography algorithm. The simulations show that the unique RT solver can accurately predict the time-dependent propagation of excitation and emission photons in diffuse as well as transport limited systems. Furthermore, the need for the accurate modeling of incident excitation illumination and the acceptance angle of the detector is demonstrated
