A portable non-invasive way to detect oral cancer
Subject – Science and Tech
Context – Scientists from IIT Kharagpur have developed a portable, user-friendly, and non-invasive device for detecting oral cancer in resource-constrained clinical settings.
Concept –
- Scientists from IIT Kharagpur have developed a portable, user-friendly, and non-invasive device for detecting oral cancer in resource-constrained clinical settings.
- This is a low-cost, handheld imaging device to screen oral cancer and pre cancer 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.
- Cancer of the oral cavity remains one of the major causes of morbidity and mortality in socially-challenged and underserved communities. There is an 80 per cent chance on average of a five-year survival rate if diagnosed early; the survival rate drops to 65 per cent or less in more advanced stages of the disease.
- The technology is currently available for ready licensing to companies for commercial adaptation. It may be subjected to more extensive statutory field trials before clinical use, which could take about two years from now.
- The estimated cost per device is within $500.
