New camera can see through human body

The new camera works by detecting light sources inside the body, such as the illuminated tip of the endoscope's long flexible tube.

Prof Kev Dhaliwal, of the University of Edinburgh, said: "The ability to see a device's location is crucial for many applications in healthcare, as we move forwards with minimally invasive approaches to treating disease."

The new camera can detect individual particles, called photons, and is so sensitive it can catch tiny traces of light passing through tissue.

It can also record the time taken for light to pass through the body, meaning the device is able to work out exactly where the endoscope is.

The project - led by the University of Edinburgh and Heriot-Watt University - is part of the Proteus Interdisciplinary Research Collaboration, which is developing a range of new technologies for diagnosing and treating lung diseases.

Dr Michael Tanner, of Heriot-Watt University, said: "My favourite element of this work was the ability to work with clinicians to understand a practical healthcare challenge, then tailor advanced technologies and principles that would not normally make it out of a physics lab to solve real problems." bbc.com
