Fig. 1.20 The mean Raman spectra of normal bronchial tissue (n D 12) and malignant adeno-
carcinoma (n D 6) and squamous cell carcinoma ( SCC , n D 10) bronchial tissue samples. Each
spectrum was normalized to the area under the curve to correct the variations in absolute spectral
intensity (Adapted from Huang et al. [ 38 ], with permission)
Fig. 1.21 In vivo NIR Raman spectra of human lung tissue with different pathologies taken with
the HF grating (2-s integration). a ( main graph ): smoothed raw spectra. a ( inset ): unprocessed raw
data. b extracted Raman spectra (spectral response calibrated and normalized). The data above
3;100 cm 1 have been scaled by 0.25. The spectra were shifted along y axis for clarity. Top to
bottom order: SCC , CIS , moderate dysplasia, and normal tissue for both a and b (Adapted from
