Information Systems in Medical Settings: A Covid-19 Detection System Using X-Ray Scans

Beginning in 2020, the new coronavirus began to expand globally. Due to Covid-19, millions of individuals are infected. Initially, the availability of corona test kits was problematic. Researchers examined the present scenario and developed the Covid-19 X-ray scan detection system. In terms of Covid-19 detection, artificial intelligence (AI)-based solutions give superior outcomes. Many AI-based models can not provide optimum results because of the issue of overfitting, which has a direct impact on model efficiency. In this work, we developed the CNN-based classification method based on the pre-trained Inception-v3 for normal, viral pneumonia, lung opacity, and Covid-19 samples. In the suggested model, we employed transfer learning to produce promising results for binary class classification. The presented model attained impressive outcomes with an accuracy of 99.42% for Covid-19 vs. Normal, 99.01% for Covid-19 vs. Lung Opacity, and 99.8% for Covid-19 vs. Viral Pneumonia, and 99.93% for Lung Opacity vs. Viral Pneumonia. Comparing the suggested model to existing deep learning-based systems indicated that ours was better. © 2022 IEEE.

Smart Health Care System for Early Detection of COVID-19 Using X-ray Scans

The novel Coronavirus spread in the world in December 2019. Millions of people are infected due to this disease. Due to viral illness, daily life routines and the economy are affected in many countries. According to a clinical study, the disease directly attacks the lungs and disturbs the respiratory system. X-ray and CT scans are the main imaging techniques to discover that disease. However, X-ray scans cost is low as comparatively CT scans. In the limited resources, deep learning plays a key role in diagnosing the COVID-19 with the help of X-ray scans. This study proposed a new transfer learning approach based on the convolutional neural network (CNN). We used the four different classes during the experimental process: COVID-19, pneumonia, lung opacity, and viral pneumonia. We also compared our proposed model with other transfer learning-based techniques. Our proposed COVID-TL model attained the best results in terms of classification. The proposed model is a beneficial tool for radiologists to get the early diagnosis results and help the patients in their early stages. © 2022 IEEE.

An Intelligent Information System and Application for the Diagnosis and Analysis of COVID-19

The novel coronavirus spread across the world at the start of 2020. Millions of people are infected due to the COVID-19. At the start, the availability of corona test kits is challenging. Researchers analyzed the current situation and produced the COVID-19 detection system on X-ray scans. Artificial intelligence (AI) based systems produce better results in terms of COVID detection. Due to the overfitting issue, many AI-based models cannot produce the best results, directly impacting model performance. In this study, we also introduced the CNN-based technique for classifying normal, pneumonia, and COVID-19. In the proposed model, we used batch normalization to regularize the mode land achieve promising results for the three binary classes. The proposed model produces 96.56% accuracy for the classification for COVID-19 vs. Normal. Finally, we compared our model with other deep learning-based approaches and discovered that our approach outperformed. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Smart COVID-3D-SCNN: A novel method to classify x-ray images of COVID-19

The outbreak of the novel coronavirus has spread worldwide, and millions of people are being infected. Image or detection classification is one of the first application areas of deep learning, which has a significant contribution to medical image analysis. In classification detection, one or more images (detection) are usually used as input, and diagnostic variables (such as whether there is a disease) are used as output. The novel coronavirus has spread across the world, infecting millions of people. Early-stage detection of critical cases of COVID-19 is essential. X-ray scans are used in clinical studies to diagnose COVID-19 and Pneumonia early. For extracting the discriminative features through these modalities, deep convolutional neural networks (CNNs) are used. A siamese convolutional neural network model (COVID-3D-SCNN) is proposed in this study for the automated detection of COVID-19 by utilizing X-ray scans. To extract the useful features, we used three consecutive models working in parallel in the proposed approach. We acquired 575 COVID-19, 1200 non-COVID, and 1400 pneumonia images, which are publicly available. In our framework, augmentation is used to enlarge the dataset. The findings suggest that the proposed method outperforms the results of comparative studies in terms of accuracy 96.70%, specificity 95.55%, and sensitivity 96.62% over (COVID-19 vs. non-COVID19 vs. Pneumonia). © 2022 CRL Publishing.

Real-time privacy preserving framework for Covid-19 contact tracing

The recent unprecedented threat from COVID-19 and past epidemics, such as SARS, AIDS, and Ebola, has affected millions of people in multiple countries. Countries have shut their borders, and their nationals have been advised to self-quarantine. The variety of responses to the pandemic has given rise to data privacy concerns. Infection prevention and control strategies as well as disease control measures, especially real-time contact tracing for COVID-19, require the identification of people exposed to COVID-19. Such tracing frameworks use mobile apps and geolocations to trace individuals. However, while the motive may be well intended, the limitations and security issues associated with using such a technology are a serious cause of concern. There are growing concerns regarding the privacy of an individual's location and personal identifiable information (PII) being shared with governments and/or health agencies. This study presents a real-time, trust-based contact-tracing framework that operates without the use of an individual's PII, location sensing, or gathering GPS logs. The focus of the proposed contact tracing framework is to ensure real-time privacy using the Bluetooth range of individuals to determine others within the range. The research validates the trust-based framework using Bluetooth as practical and privacy-aware. Using our proposed methodology, personal information, health logs, and location data will be secure and not abused. This research analyzes 100,000 tracing dataset records from 150 mobile devices to identify infected users and active users. © 2021 Tech Science Press. All rights reserved.
