Forward Models of Light Transport in Biological Tissue 329
visible is the good agreement between measurements and trans-
port simulations. e diusion-theory-based simulation diers
signicantly from measurements and transport simulations.
More details and additional results can be found in Klose et al.
(2002) and Hielscher et al. (1998).
16.4.2 Inuence of Collimated Light Sources
(Delta-Eddington Approach)
Light sources used in medical application are typically colli-
mated (e.g., a laser beam that hits the surface of a tissue). e
importance of modeling this light source accurately is illus-
trated in the following example. ...
