Scientists developed a system to detect light produced by medical instruments in the human body


The new device is able to detect sources of light  inside the body, such as the illuminated tip of the endoscope’s long flexible tube. This is new and important because until now it has not been possible to track where an endoscope is located in the body in order to guide it to the right place, in common  conditions. The new camera takes advantage of advanced technology that can detect individual particles of light, called photons.

This device has thousands of single photon detectors integrated onto a silicon chip. “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,” says Kev Dhaliwal of the research team. Early tests have demonstrated that the prototype device can track the location of a point light source through 20 centimeters of tissue under normal light conditions. I hope we can continue this interdisciplinary approach to make a real difference in healthcare technology,” Dr Michael Tanner of Heriot-Watt’s School of Engineering and Physical Sciences said: The research was published in the journal Biomedical Optics Express.
