Terahertz spectral unmixing based method for identifying gastric cancer.

In this study, based on a modified hard modeling factor analysis (HMFA) method, terahertz spectral unmixing was applied to investigate the relationships between the absorption spectra in terahertz time-domain spectroscopy (THz-TDS) and certain biomarkers of gastric cancer in order to systematically identify gastric cancer. A probability distribution and box plot were used to extract the distinctive peaks that indicate carcinogenesis, and the corresponding weight distributions were used to discriminate the tissue types. The results of this work indicate that terahertz techniques have the potential to detect different levels of cancer, including benign tumors and polyps.
