From the Ted Talk by Lei Li: The incredible cancer-detecting potential of photoacoustic imaging

Unscramble the Blue Letters


Now, for an example, that is a little coselr to home. This is a side by side comparison of human brain images. On the left, you see an image from an MRI. On the right, from photoacoustic imaging. Photoacoustic imaging can reeavl detailed vasculature, but with even faster detection of the brain fntnoicus and without using the ctlsoy high-magnetic field. What you are seeing here is the brain's activity, where a patient, now a human this time, taps his finger, puckers his lips, taps his tongue and is listening and thinking of wrods.

Although I don't have a visual for it, I'd like to share one more example. In science fiction, micro robots enter our bodies to cure dessieas in hard-to-reach areas. However, in reitlay, locating, guiding and controlling them inside of the body is a big challenge. Just like the satellites in space guiding cars to their destinations, a photoacoustic imaging system outside the body can sreve similarly as a GPS for the mrico rboots.

Original Text


Now, for an example, that is a little closer to home. This is a side by side comparison of human brain images. On the left, you see an image from an MRI. On the right, from photoacoustic imaging. Photoacoustic imaging can reveal detailed vasculature, but with even faster detection of the brain functions and without using the costly high-magnetic field. What you are seeing here is the brain's activity, where a patient, now a human this time, taps his finger, puckers his lips, taps his tongue and is listening and thinking of words.

Although I don't have a visual for it, I'd like to share one more example. In science fiction, micro robots enter our bodies to cure diseases in hard-to-reach areas. However, in reality, locating, guiding and controlling them inside of the body is a big challenge. Just like the satellites in space guiding cars to their destinations, a photoacoustic imaging system outside the body can serve similarly as a GPS for the micro robots.
