This is detailed enough to spot the first signs of tumors in specific cells and is about 100 times higher resolution than what X-Ray, computed tomography (CT) and Magnetic Resonance Imaging (MRI) machines can provide.
The technology behind the device is a result of six years of optical imaging research and was jointly developed by a team from NTU with researchers at the Harvard Medical School and the University of Alabama, U.S.A.
The device is based on new imaging technology known as micro 'Optical Coherence Tomography' (OCT), the device emits a spectrum of light between 700 to 950 nanometres, known as near-infrared light. At that level the light source is able to penetrate human tissue and organs.
The researchers led by Associate Professor Liu Linbo, designed the handheld device to be used by non-imaging professionals at the bedside, allowing them scan patients without scheduling and transporting to MRI, CT or other imaging facilities.
The prototype device has undergone clinical trials at Wuhan University's Endoscopic Centre, and has shown promise in detecting abnormal colon polyps to the same level of accuracy as trained pathologists.
