Scientists from the Fraunhofer Project Group for Automation in Medicine and Biotechnology have developed a multispectral fluorescence camera system that may prove useful in surgery to remove tumors. The system visualizes fluorescent dyes that bind to cancerous tissue, allowing surgeons to distinguish it from healthy tissue. "The operator receives significantly more accurate information. Millimeter-sized tumor remnants or metastases that a surgeon would otherwise possibly overlook are recognizable in detail on the monitor. Patients operated under fluorescent light have improved chances of survival," said researcher Nikolas Dimitriadis.
