December 27, 2017, 6:55 pm Researchers from the Indian Institute of Science Education and Research (IISER), Kolkata and Indian Institute of Technology (IIT) Kanpur have developed Artificial Intelligence that can detect cancer tissues in its primitive stages within minutes. And they are using light to detect this!

Differences in the structure and formation of healthy and precancerous tissues change their refractive index and make them scatter light in discernible variations. Although this minute difference cannot be detected by the naked eye, these researchers have developed algorithms that can.

Additionally, the algorithms go a step further and identify the stage of cancer, with accuracy levels exceeding 95%.

He spoke to this ground-breaking algorithm to The Hindu. “The microstructure of normal tissue is uniform, but as [the] disease progresses, the tissue microstructure becomes complex and different.

Based on this correlation, we created a novel light scattering-based method to identify these unique microstructures for detecting cancer progression,” he said. This biomarker has two parameters—Hurst exponent and width of singularity spectrum. Read more from…
