Systematic studies of fractal dimension parameters, absorption and scattering coefficients for cancerous and normal prostate tissues

摘要

The optical coefficients (μ_s, μa, μ'_s and g) of human cancerous and normal prostate tissues were investigated and compared in the spectral range of 750nm - 860 nm. The fractal dimensional parameters including fractal dimension (D_f), cutoff diameter (d_(max)) and the most efficient diameter (d_m) between the cancerous and normal prostate tissues were determined based on the extinction and diffusion reflection intensity measurements and the determination of μ_s, μ_a, μ'_s and g. The results are in good agreement with prostate cancer evolution defined by Gleason Grades. The difference of fractal dimensional parameters and optical coefficients of cancerous and normal prostate tissues may present a potential criterion for prostate cancer detection.
