Developed camera that allows to see through the human body


This new device is able to detect light sources within the human body, such as the illuminated tip of the endoscope.

Scientists at the University of Edinburgh and Heriot-Watt University in Scotland have developed this innovative camera that lets you see through the human body.

The device was designed with the intention of helping physicians to follow instruments such as the endoscope, which are used inside the human body: able to detect light sources inside the body, such as the illuminated tip of the flexible tube of the endoscope, used for digestive system.

Until now it was not yet possible to detect exactly where the endoscope was inside the human body, in order to guide the equipment to the exact and necessary place, without using equipment like the X-ray. But even if this method does not allow a clear picture of the location of the endoscope, as light beams are dispersed or rejected by tissues and organs.

This new camera enables precise location of the device by trapping individual light particles through thousands of detectors placed on a silicon chip.

In statements quoted by the University of Edinburgh website, Professor Kev Dhaliwal said the new device has “a lot of potential” in medicine, since “the ability to see the location of a device is crucial for many applications in healthcare, as we move forward with minimally invasive approaches to the treatment of diseases”.

“My favorite element in this work was the ability to work with clinicians and understand a real health challenge in order to adapt new technologies and advanced principles that would not otherwise leave the physics laboratory to solve real problems”, he said. Dr. Michael Tanner of Heriot-Watt University.

“I hope we can continue with this interdisciplinary approach in order to make a real difference in the technology used in healthcare”, he added.

Initial tests have shown that the prototype of the new device can track the location of a point source of light through 20 centimeters of tissue under normal light conditions.
