Correct Answer : Option (B) - IIT Kharagpur
Scientists from IIT Kharagpur have developed a portable, user-friendly, and non-invasive device for detecting "oral cancer" in resource-constrained clinical settings.
Experts from the Guru Nanak Institute of Dental Sciences and Research in West Bengal supervised the clinical trials, and have established the efficacy of the new method in differentiating cancerous and precancerous stages of suspected oral abnormalities, as verified by high-standard biopsy reports.
The research has been published recently in the prestigious Proceedings of the National Academy of Sciences (PNAS), USA. (‘Portable, handheld, and affordable blood perfusion imager for screening of subsurface cancer in resource-limited settings’: Arka Bhowmik, Suman Chakraborty, and others)
“This is a low-cost, handheld imaging device to screen oral cancer and precancer based on measured change in blood flow rate of the tissue from thermal imaging and analytics. The blood perfusion imager, which combines a miniature far-infrared camera and a humidity sensor, are electronically controlled and interfaced with a combined physics-based and data-driven software engine,” Prof Suman Chakraborty of the Department of Mechanical Engineering at IIT-Kharagpur told..
