Can you see what I see? Maybe not, but the computer can

What if you could just look at someone’s face and tell how fast his or her heart is beating?

The question isn’t as far-fetched as you might think. The movement of our beating heart inside our chest can in fact reveal itself on the surface of the skin, albeit too faintly for our eyes to see.

It uses computer-based video processing to make a pulse look like it’s bulging on a person’s wrist, or to amplify changes in skin color as freshly oxygenated blood gets pumped through the body.

Walking out of the hospital at his shift’s end, Imam found himself wishing there were an easy way to visualize, in real time, the progress of lines that advance deep into the body through a child’s veins.

If only we could make these lines light up, he thought to himself….
