A Sensitive Fibre Optic Probe for Autofluorescence Spectroscopy of Oral Tongue Cancer: Monte Carlo Simulation Study

Table 1

Optical properties of tissue layers in normal and dysplastic tongues. FE is the fluorescence efficiency which is the multiplication of the quantum yield and fluorophore absorption coefficient, and fluorescence intensity is the normalized relative fluorescence intensities based on quantitative analysis of the confocal fluorescence images [22].
