Shimadzu’s Lightvision Imaging System to Support Breast Cancer Treatment

Shimadzu Corporation has entered the medical near-infrared camera market with the release of the new Lightvision near-infrared fluorescence imaging system that is designed to support breast cancer treatment through the visualization of lymph vessels and blood vessels based on the detection of near-infrared fluorescent light emitted from indocyanine green (ICG).

The new Lightvision system creates real time contrast images of lymph vessels below tissue surfaces by administering ICG through the lymph vessels, exposing the corresponding tissue to excitation light, and then detecting and visualizing the slight emission of near-infrared light from the ICG, which is invisible to the naked eye.

By visualizing the lymph vessels during surgery, the surgeon can perform surgical procedures while monitoring the position of lymph vessels being excised, for example, on a monitor screen.

This is especially useful for identifying the position of sentinel lymph nodes, which are important for diagnosing the metastasis status of cancer cells during breast cancer surgery.
