Camera watches internal organs up to 20 cm deep

The researchers developed camera to watch internal organs. A camera to view the inside of the human body without the need for infra-red procedures and costly X-ray imaging. The prototype cameras designed by the team of researchers Heriot-Watt University and the University of Edinburgh are able to watch up to 20 cm into human tissues.

The camera is designed to help doctors track medical devices known as endoscopes used to investigate internal conditions. The new device is capable of detecting light sources inside the body, such as the end of an illuminated endoscope flexible tube.

The light from the endoscope pass through the body, but it usually spreads or bounces off tissues and organs rather than traveling straight. It makes it almost impossible to get a clear picture of where the endoscope is.

The new camera utilizes advanced technology that detect individual light particles called photons. Experts have integrated thousands of single photon detectors onto a silicon chip, similar to those found in digital cameras. The team reported the findings to the journal Biomedical Optics Express.

This technology is so sensitive that it can detect small light traces that pass through body tissues from endoscopic light. It also record the time it takes light to pass through the body and allow the device to detect scattered light.

"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," said Kev Dhaliwal, Professor of Molecular Imaging and Healthcare Technology, University of Edinburgh and Clinical Lead, Proteus.

Initial tests have shown prototype devices can track the location of a point light source through a 20 cm network in normal light conditions. This project is part of the Proteus Interdisciplinary Research Collaboration to develop a revolutionary for lung therapy.

"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," said Michael Tanner of Heriot-Watt University.
