After BlueDot's AI epidemiologist was one of the first to signal the outbreak of the coronavirus (Covid 19), another AI-based software developed by a Beijing-based startup Infervision, is now helping physicians diagnose it in Wuhan.
The software, developed in collaboration with Wuhan Tongji Hospital, helps detect typical and partial symptoms of Covid 19 by looking for signs of pneumonia. While the team already had models that detected pneumonia in place, after the outbreak of the virus, they were updated to look out specifically for coronavirus pneumonia.
To train the model, more than 2,000 CT images from the early Chinese affectees of the outbreak were analyzed using NVIDIA V100 GPUs. To develop the software, Infervision used NVIDIA Clara, which is an application framework for AI-powered medical imaging and genomics. For inference, the models employ NVIDIA T4 GPUs.
Infervision's software has been deployed in more than 34 hospitals across China and is currently under evaluation in the United States and Europe. So far, it has helped review more than 32,000 potential cases of Covid 19.
The AI-based software's primary advantage lies in the fact that since symptomatic patients are piling up in hospitals, its fast diagnosis can help triage the patients quickly. The software also fares well in cross-comparison and in analyzing the development of lungs over multiple examinations.
