Abstract
Using a spectrophotometer equipped with an internal integrating sphere , the absorption (mu a) and the reduced scattering (mu s') coefficient s of ex vivo human colon tissues were evaluated from reflectance and t ransmittance measurements. mu a and mu-s' varied from 47.7 to 1.0 cm(- 1) and from 14.2 to 6.2 cm(-1), respectively, on passing from 300 nm t o 800 nm. These results can be used to estimate the optical penetratio n depths when photodynamic therapy or light-induced fluorescence proce dures are used. (C) 1994 Wiley-Liss, Inc.
