Researchers at the University of Leicester have created a new AI tool that can detect COVID-19.

The software analyzes chest CT scans and uses deep learning algorithms to accurately diagnose the disease. With an of 97.86%, it's currently the most successful COVID-19 diagnostic tool in the world.

Currently, the diagnosis of COVID-19 is based on nucleic acid testing, or PCR tests as they are commonly known. These tests can produce and results can also be affected by hysteresis—when the physical effects of an illness lag behind their cause. AI, therefore, offers an opportunity to rapidly screen and effectively monitor COVID-19 cases on a large scale, reducing the burden on doctors.

Professor Yudong Zhang, Professor of Knowledge Discovery and Machine Learning at the University of Leicester says that their "research focuses on the automatic diagnosis of COVID-19 based on random graph . The results showed that our method can find the suspicious regions in the chest images automatically and make accurate predictions based on the representations. The accuracy of the system means that it can be used in the clinical diagnosis of COVID-19, which may help to control the spread of the virus. We hope that, in the future, this type of technology will allow for automated computer diagnosis without the need for manual intervention, in order to create a smarter, efficient healthcare service."

Researchers will now further develop this technology in the hope that the COVID computer may eventually replace the need for radiologists to diagnose COVID-19 in clinics. The software, which can even be deployed in such as , will also be adapted and expanded to detect and diagnose other diseases (such as breast cancer, Alzheimer's Disease, and cardiovascular diseases).

The research is published in the International Journal of Intelligent Systems.
