How we can use light to see deep inside our bodies and brains
Summary
A new technology that the speaker invented is a system that you can see deep inside your bodies and brains by using red light and sound. It can track tumors, measures neural activity, and can possibly replace the MRI machine with a cheaper, efficient and wearable system.

It can say that it's extraordinary at finding blood, in fact, blood absorbs light and flesh scatters light. For example, you can see tumors that has five times the amount of blood as normal flesh, whether blood carries oxygen or not and deep inside of lungs by using the new system that she invented.

It means that you can detect early cancer, pneumonia, and stroke. 1)

Light and sound will become compact, portable, inexpensive medical machines, 2) and can reach your brain through your skull, you know, it can say this is brain-computer communication without surgery or implants.

This invention has many possibilities.
