Lei Li: The incredible cancer-detecting potential of photoacoustic imaging

The incredible cancer-detecting potential of photoacoustic imaging

Could we use the energy from light and sound to detect disease? TED Fellow Lei Li shares the exciting promise of photoacoustic imaging: an affordable, painless and accurate method of converting light into sound in order to create high-resolution images of what's going on inside our bodies. From early detection of breast cancer to steering medicine-delivering micro-robots, learn how this cutting-edge technology could open up a new world of possibility when it comes to seeing, tracking and diagnosing disease.

Photoacoustic imaging is set to transform how diseases like cancer are detected and understood. By converting light into sound, this technology produces high-resolution images with remarkable speed and clarity, taking just 15 seconds to scan the entire breast in 3D. Unlike traditional methods, it is painless, affordable, and non-invasive, with no need for contrast agents. Its applications extend beyond cancer, offering real-time insights into brain function and even the potential to steer micro-robots inside the human body.
