Abstract :
By using laser-induced Raman spectrum technology, we researched the spectrum characteristic of relative normal human, atrophic gastritis and stomach cancer spectra except esophagus cancer. The intensity of each of three sharp peaks (A, B and C) can characterize all peak was different in different spectrum. And we differentiated the spectrum of these three cases. A notable difference is that the intensity of peak C excited by 488.0 nm is higher than excited by 514.5 nm in spectrum of stomach cancer, whereas lower in other cases. We utilized it as a criterion and got an accuracy of 80.77% in stomach cancer detection. Results showed that it is available of detection of stomach cancer and pre-stomach cancer.
