Ever since the onset of the pandemic COVID-19, the members of the centre discusses the research progress across global in the aspect of medical imaging to detect COVID-19 through various imaging modalities like X-Ray. Ultrasound and CT scan. Initially, we were thinking to use ultrasound images but due to some technical issues, we couldn’t follow it up.
Later we decided to use chest X-ray images and incidentally, we were able to get around 100 COVID-19 affected subjects’ chest X-ray images through open-source Canadian research forum. With the acquired images we planned to develop an Artificial Intelligence (AI) tool to detect COVID-19 condition from the test chest X-ray image.
We decided to add the provision for detecting CAP (Community-Acquired Pneumonia) besides to COVID-19 in the proposed tool. The reason for the inclusion of CAP is that there is a relatively high possibility of getting this condition. We have decided to detect the normal conditions also. Hence, we decided to develop a three-class classifier using that we can detect COVID-19, CAP and normal condition from the test X-ray image.
We acquired the necessary CAP & normal chest X-ray images through RSNA (Radiological Society of North America) for training the AI tool. We used 14,148 chest X-ray images of all these three classes for rigorously training the neural network inbuilt in the AI tool. The training process underwent different iterations until we reach a training accuracy of 99.9. In the testing process, 1661 images were used and by adopting different strategies we are able to get a testing accuracy of 95.4.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) coronavirus, which first surfaced in Wuhan, China, word wipe in December 2019, is the infectious disease that causes the coronavirus illness 2019 [1]. This disease has a high rate of morbidity and mortality and is rapidly expanding around the world.

great
This product is a machine learning application that was developed after a computer program examined thousands of chest X-ray pictures and predicted with up to 80% accuracy the patient's life-threatening progression over wordle game the course of the next four days. With this device, the authors give clinicians a way to quickly identify which COVID-19 patients are at risk for potentially fatal consequences, enabling them to be more proactive in their treatment and care and lowering death rates.

good
Medical workers frequently subway surfers employ a chest X-ray for COVID-19 infections since it is a simple and standard imaging diagnostic.

yep
The development of an Artificial Intelligence (AI) drive mad tool to detect COVID-19 condition from a chest X-ray image is an active area of research in the field of medical imaging and computer vision. The use of AI tools for COVID-19 detection can help healthcare professionals to quickly and accurately identify patients with the virus, allowing for early treatment and isolation.
