Brazil Institute of physics, University of São Paulo, Carlos has recently developed a new cancer tracking system.Developers said, this innovation will help surgeons more precisely the cancerous cells, optimizing treatment, and effects.

According to reports, this device the working principle is based on a number of substances are subject to specific wavelengths of light, will fluoresce after absorbing energy.So the new equipment fluorescent powder delivered to the site of the cancer in the lymph nodes, and then with a specific color of light as a part of Phosphors emit different colors of light are device cameras, surgical staff in real time on the display to determine the first lymph node metastasis through, location of the Sentinel lymph node.Main components of equipment including two cameras, capturing black and white images, the other for viewing color images;Another group used to detect fluorescence and infrared device and a display of the captured image.
