The ability to safely see inside our bodies is one of the most important breakthroughs in medical history, but it hasn’t come without risk. What if there was a safer way to do so that didn’t rely on radiation? What if there were a smaller-scale, more portable way? It seems like that way might be here, with incredible technology called “Vein Viewer” that uses harmless, near-infrared light to bring images of blood below the skin right to the surface. Watch it in action; it’s pretty incredible.
