A new, multispectral fluorescence camera system, developed by researchers at the Fraunhofer Project Group for Automation in Medicine and Biotechnology (PAMB), which belongs to the Fraunhofer Institute for Manufacturing Engineering and Automation (IPA), can display fluorescent molecules that “paint” cancer tissue. These are injected into the patients blood circulation prior to surgery and selectively attach onto the tumor during their trip through the body. If the corresponding area is then illumimated with a specific wavelength, fluorescence is emitted and the malignant tissue glows green, blue, red, or any other color, depending on the injected dye, while the healthy tissue appears the same. In this way, the surgeon can see clusters of tumors cells that cannot be recognized by the naked eye.
