A new AI-driven platform will now help early intervention through rapid screening of COVID 19 with the help of Chest X-ray interpretation over WhatsApp for doctors who have access to X-ray machines. The solution called XraySetu can work with low-resolution images sent via mobiles, is quick and easy to use, and can facilitate detection in rural areas.

ARTPARK (AI & Robotics Technology Park), a not-for-profit foundation established by the Indian Institute of Science (IISc), Bengaluru, with support from the Department of Science & Technology (DST), Govt. of India, in collaboration with Bangalore-based HealthTech startup Niramai and the Indian Institute of Science (IISc), has developed XraySetu specifically designed to identify COVID positive patients even from low-resolution Chest X-Ray images sent over Whatsapp.

“It also has semantic annotations of affected areas for review and localized heatmap by doctors to help them verify it easily with other modalities and has already served close to 1200+ reports so far from the interior parts of India,” stated a release.

WhatsApp-based chatbot

Commenting on the new platform, Mr. Umakant Soni, Founder, and CEO, ARTPARK, said, “We need to scale technology for addressing the needs of 1.36 billion people, especially considering we have 1 radiologist for over 1 million people here. Built with the collaboration of industry and academia, XraySetu paves the way for exponential technologies like AI to leapfrog and provide cutting-edge healthcare technology to rural India in an extremely cost-effective manner.”

To conduct the health check, any doctor simply needs to visit www.xraysetu.com and click on the ‘Try the Free XraySetu Beta’ button. The platform will then redirect the person to another page, wherein he or she can choose to engage with the WhatsApp-based chatbot via web or smartphone application. Or the doctor can simply send a WhatsApp message to the phone number +91 8046163838 to start the XraySetu service. Then they just need to click the picture of the patient’s X-ray and obtain the 2-page automated diagnostics with annotated images in a few minutes. While extending the probability of the COVID-19 contraction, the report also highlights a localized heatmap for a quick perusal of the doctor.

“NIRAMAI has partnered with ARTPARK and IISc to provide a rapid COVID screening method for rural doctors who have access to X-ray machines. XraySetu provides an automated interpretation of Chest X-Rays to predict if a patient has any lung abnormality that indicates COVID-19 infection,” said Dr. Geetha Manjunath, Founder, and CEO, Niramai.

Tested and validated with over 1,25 000 X-ray images from National Institute of Health, UK, as well as over 1000+ Indian COVID patients from, XraySetu, has shown excellent performance with Sensitivity: 98.86%, and Specificity: 74.74%

Besides COVID-19, the platform can also detect 14 additional lung-related ailments, including tuberculosis and pneumonia, alongside others. It can further be used for both analog and digital X-rays and has been successfully piloted by more than 300 doctors in rural areas over the last 10 months.
