MIT Develops Optical Imaging System to Pinpoint Tumors

To detect cancer at early stage is critical for treatment. In order to spot tumors before they become too big to cure, researchers at Massachusetts Institute of Technology (MIT) developed an optical imaging system using near-infrared light to spot tiny tumors. The MIT research team noted that near-infrared light with wavelengths from 900 to 1700 nanometers, is suitable to tissue imaging because light with longer wavelengths does not scatter as much as when it strikes objects, allowing the light to penetrate deeper into the tissue. Using the advantage of near-infrared light, r...
