Doctors in India are now able to diagnose Covid-19 infection on a real-time basis, as with the help of a new Artificial Intelligence (AI) driven platform XraySetu they get access to chest X-rays and can interpret their results over WhatsApp.
A new AI-driven platform is now helping in early intervention through rapid screening of Covid 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.
As the novel coronavirus continues to wreak havoc across the rural heartlands of India, it has become critical to drive rapid testing, contact tracing, and create dedicated containment zones. At a time when such tests are taking more than a week across some cities, the challenge is even more for rural areas. Easy alternative tests are necessary as RT-PCR tests also give a ‘false negative’ for some variants.
What is XraySetu
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.
How does XraySetu work
1) To conduct the health check, any doctor simply needs to visit www.xraysetu.com and click on the ‘Try the Free XraySetu Beta’ button.
2) 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.
3) Or the doctor can simply send a WhatsApp message to the phone number +91 8046163838 to start the XraySetu service.
4) The doctor just needs to click the picture of the patient’s X-ray and obtain the 2-page automated diagnostics with annotated images in a few minutes.
XraySetu efficacy
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%
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.
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 analogue and digital X-rays and has been successfully piloted by more than 300 doctors in rural areas over the last 10 months.
