According to a study published in the Biomedical Optics Express, the technology can detect light source emitted from endoscope’s long and flexible illuminated tip. This technology is set to replace expensive procedures like X-rays.
Light from the endoscope can pass through the body, but usually scatters and bounces off the tissues and organs instead of travelling straight. This does not give a clear picture of the endoscope’s location inside the body.
The new camera can take advantage of the endoscope’s location, and can detect individual particles of light known as photons.
As per researchers, the device’s location is crucial for various applications in healthcare. Scientists are continually looking for minimally invasive approaches to treating diseases.
Scientists have integrated thousands of single photon detectors onto a silicon chip, akin to the one found in a digital camera.
The technology is sensitive enough to detect the tiny traces of light passage through the body’s tissue from the light of the endoscope. It can also record the time registered for the light to pass through the body. The device can also detect scattered light.
Equating the direction of the straight light and the scattered light, the technology can determine the exact location of the endoscope inside the body.
Kev Dhaliwal, Professor at University of Edinburg in Scotland, said, “This is a facilitating technology that enables us to see through the human body. It has a massive potential for diverse applications such as seeing through the body.”
As per early experiments, the prototype device could locate the point light source through 20 centimeters of tissue under normal light conditions.
