| Abstract | ||
| Early detection of COVID-19 based on chest CT will enable timely treatment of patients and help control the spread of the disease. With rapid spreading of COVID-19 in many countries, however, CT volumes of suspicious patients are increasing at a speed much faster than the availability of human experts. Here, we propose an artificial intelligence (AI) system for fast COVID-19 diagnosis with an accuracy comparable to experienced radiologists. A large dataset was constructed by collecting 746 CT volumes of 359 patients with confirmed COVID-19 and 387 negative cases from publicly available chest CT datasets. In this paper, we propose a deep learning architecture to detect Covid-19 Coronavirus in CT Images. This architecture contains one network to classify images as either Covid-19 or Non-Covid-19. The experiment results evaluated by three parameters including accuracy, sensitivity, and specificity. For the ResNet-50 deep learning, these outcomes refer to the maximum sensitivity being 91.69% by the training dataset for the ResNet-50. ResNet-50 can be considered as a high sensitivity model to characterize and diagnose Covid-19 Coronavirus and can be used as an adjuvant tool in radiology departments. | ||
