An Indian-origin scientist has led a team at a UK university to create a medical camera that can see through the human body, and he believes it has immense potential for doctors in tracking internal examinations. Kev Dhaliwal, Professor of Molecular Imaging and Healthcare Technology at the University of Edinburgh, believes that with this device doctors will no longer be required to exclusively rely on expensive scans and X-rays. 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 one moves forwards with minimally invasive approaches to treating disease,” said Dhaliwal, the Project Lead of Proteus, which is part of a larger research collaboration developing a range of new technologies. The camera is designed to help doctors track medical tools, known as endoscopes, that are used to investigate a range of internal conditions. The new device is able to detect sources of light inside the body, such as the illuminated tip of the endoscope`s long flexible tube. The new camera takes advantage of advanced technology that can detect individual particles of light, called photons.
