Discrimination of Nasopharyngeal Carcinoma from Noncancerous Ex Vivo Tissue Using Reflectance Spectroscopy
Figure 2
Mean reflectance spectra from NPC (red line, ) and noncancerous ex vivo tissue (blue line, ). Asterisks indicated significant difference ( value < 0.05) after -test, in which the values are 0.006 and 1.6 × 10−4 for 540 nm and 576 nm, respectively. Areas (shaded) illustrate the respective standard deviations of the means spectra.
