Abstract

We investigate optical signatures of normal and cancer tissues by measuring nine cases of oral squamous cell carcinomas transplanted into tongue of nude mice. Transmission results were measured with a spatially translated fiber probe for auto-fluorescence spectra of normal and cancer specimens in 450-750 nm. Normal and cancer specimens were quantitatively compared based on extinction coefficients (μ_t) calculated by collimated transmission method. Although direct comparison of μ_t may be difficult to detect cancer specimens, it was found that use of multiple determinants based on spatial variance and a spectral ratio of μ_t shows promise for the diagnosis. The preliminary results attest the feasibility and challenges of screening precancerous oral tissues using optical detection.
