A battery operated ultra-portable handheld X-ray devices (MyBeam from MyLab) with Computer Aided Detection (CAD) (Qure.Ai, https://www.qure.ai/global-health) will be used for initial screening. Qure Ai technology has been validated and found to have performance at par with expert readers and the experience of using it in India for TB screening has been documented. At the threshold value of 0.5, the Qure AI has a sensitivity of 93% and specificity of 82%.
The ultra-portable handheld X-ray devices with CAD and Picture Archiving and Communications Systems (PACs) will be placed in the campsite, the location of which will be decided by the key stakeholders of each ward, based on the appropriateness of the site for taking chest X-rays, ease of access to the clients, and better internet connection for transferring the images for AI reading. Three radiographers assigned to arm-1 will manage the setting up of the X-ray machine and processing of X-ray images. The images of the chest X-ray will be sent to Qure AI through the Swasthya Nagaram application. Within three minutes of taking a chest X-ray, Qure Ai provides one of the three results- suggestive of TB, not suggestive of TB and non-TB abnormality.
