Abstract
With the daily rapid growth in the number of newly confirmed and suspected COVID-19 cases, COVID-19 extremely threatens public health, countries’ economic, social life, and international relations around the world. There are different medical methods to detect and diagnose this disease such as viral nucleic acid screening by using specimens of the lower respiratory tract. However, the availability of sufficient laboratory screening in the infested counties represents a critical challenge especially with the fast-spreading of COVID-19. Therefore, alternative diagnostic procedures that depend on Artificial Intelligence (AI) techniques are required in the meantime to fight against this epidemic. This paper focuses on using chest CT for diagnosis of COVID-19, as an alternative or assistive method to the reverse-transcription polymerase chain reaction (RT-PCR) tests. Motivated by this, this paper introduces a new model based on deep learning for detecting patients infected with COVID-19 using chest CT. In this paper, a new proposed model for diagnosis of COVID-19 based on using Convolutional Neural Networks (CNN) and Particle Swarm Optimization (PSO) algorithm to classify the CT chest images of patients into infected or not infected. In this paper, the network hyper-parameters in the CNN are optimized by using the PSO algorithm to eliminate the requirement of manual search and enhance the network performance. The used chest radiography dataset in this paper is described which leveraged to train COVID-Net and includes include more 16,500 chest radiography images across more 13,500 patient cases from two open access data repositories. The experimental results of this work exhibited that the suggested system accuracy ratio of 98.04% is competitive to the other models.
