Camera that Sees through the Body
“Experts have integrated thousands of single photon detectors onto a silicon chip, similar to that found in a digital camera. The technology is so sensitive that it can detect the tiny traces of light that pass through the body’s tissue from the light of the endoscope. It can also record the time taken for light to pass through the body, allowing the device to also detect the scattered light. By taking into account both the scattered light and the light that travels straight to the camera, the device is able to work out exactly where the endoscope is located in the body. This ability to see a device’s location is crucial for many applications in healthcare, as we move forward with minimally invasive approaches to treating disease.” MORE
