WEST LAFAYETTE, Ind., March 7, 2012 — Mimicking living breast tissue through the new Raman-based imaging tool of vibrational spectral microscopy reveals subtle changes and can could help assess a woman’s breast cancer risk. The imaging technique identifies and tracks certain molecules by measuring their vibration with a laser. It works at high speed to enable researchers to measure changes in real time in live tissue, said Ji-Xin Cheng, an associate professor of biomedical engineering and chemistry at Purdue University. The researchers used a special “3-D culture” that mimics living mammary gland...Read full article

    hyperspectral imaging
    Hyperspectral imaging is an advanced imaging technique that captures and processes information from across the electromagnetic spectrum. Unlike traditional imaging systems that record only a few spectral bands (such as red, green, and blue in visible light), hyperspectral imaging collects data in numerous contiguous bands, covering a wide range of wavelengths. This extended spectral coverage enables detailed analysis and characterization of materials based on their spectral signatures. Key...
    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
