Endoscopic Raman Spectroscopy for Molecular Fingerprinting of Gastric Cancer: Principle to Implementation

Figure 6

Comparison of in vivo gastric Raman spectra measured with the reconstructed tissue Raman spectra through the employment of the eight basis reference Raman spectra: (a) normal, and (b) cancerous gastric tissue. Residual of the fits are also shown on the same scale in each plot (adopted from Huang et al. Biosens Bioelectron 2010; 26: 383–389) [30].
