Scientists have developed a camera that can see through the human body.

The device has been designed to help doctors track medical tools, known as endoscopes, during internal examinations.

Until now, medics have had to rely on expensive scans, such as X-rays, to trace their progress.

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: "It has immense potential for diverse applications, such as the one described in this work.

"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."

'Tissues and organs'

Early tests have shown the prototype device can track a point light source through 20cm of tissue under normal conditions.

Beams from the endoscope can pass through the body, but usually scatter or bounce off tissues and organs rather than travelling straight through.
