Chemometrics helps analyze terahertz spectra

Hank Hogan

Investigators at Riken Institute in Sendai and at the University of Fukui, both in Japan, have demonstrated that terahertz imaging, when combined with the correct analysis techniques, could be useful as a cancer diagnostic. In three of four test samples, a terahertz imaging-based approach successfully differentiated cancerous from normal tissue. In theory, imaging with terahertz wavelengths (100 to 1000 μm) offers significant advantages for medical diagnostics. It is nonionizing, and it deeply penetrates tissue. Therefore, it offers the ability to completely image tissue samples 1.0...Read full article
