Goggles Allow Surgeons to See Tumors

Feb-14-14 A new heads-up display for surgeons allows them to see cancer cells, making it much easier for them to remove the entire tumor without damaging neighboring, healthy tissues.

The goggle display system works by taking advantage of the properties of indocyaninin green (ICG) dye, a fluorescent dye that binds to blood plasma proteins, and the highly-vascularized nature of tumors. After the dye has injected into the patient’s bloodstream, it is subjected to a special light sent out by the goggles that will make the dye glow blue. This glow can then be superimposed onto the real time surgery scene in front of the glasses. The tumors, with their larger supply of flowing blood, will glow more vividly than the surrounding tissue and allow the surgeons to better identify the cancerous tissue.
