Scotland, September 4: Scientists have developed a camera that sees through the human body. This will help doctors track internal examinations as they occur, rather than relying on expensive X-rays. The camera detects light sources within the body, such as that on the end of an endoscope.
Such light can even be detected through 20cm of tissue. The camera is also suitable for use at a patient's bedside. Prof Kev Dhaliwal, of the University of Edinburgh, said: "It has immense potential for diverse applications, such as the one described in this work.
With current methods, it can also be very difficult to find out exactly where the endoscope is because the light beams scatter or bounce off tissues and organs. But the new camera can give a precise location because it can detect individual photons and measure the time it takes for light to pass through the body.
"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 detects tiny particles of light, known as photons.
This project is the part of Proteus Interdisciplinary Research Collaboration which is developing new technologies for diagnosing and treating lung diseases.
