The proposed model was tested on two different datasets, and several experiments with different combinations were performed. As of 24th of August 2020, there have been more than 23 million confirmed cases of coronavirus worldwide, with about 800,000 of such cases resulting in the death of the infected patient. Published. Coronavirus infects both birds and mammals, but the bat is host to the largest number of the viral genotype of coronavirus. Brain Ventricle Localization And Segmentation In 3D Ultrasound Images. You can also skip this process and download intermediate generated file from Google Drive that is used in our implementation. Amyar et al. Thoracic CT scan is the imaging modality of choice that plays a vital role in the management of COVID-19. The proposed system included lung segmentation, COVID-19 detection in CT slices, and marking case as COVID-19 using a predetermined threshold based on the counted COVID-19 positive slices. The non-COVID-19 pneumonia group includes other types of pneumonia, which is not caused by COVID-19, such as viral or bacterial pneumonia, as well as influenza A and SARS.

This is a collection of COVID-19 imaging-based AI research papers and datasets. It was concluded that FCONet based on ResNet-50 outperformed other pretrained models and achieved 96.97% of accuracy in the external validation data set of COVID-19 pneumonia images. We elaborately collect COVID-19 imaging-based AI research papers and datasets awesome-list. Class. The considered CT dataset consists of 521 COVID-19 infected images, 397 healthy images, 76 bacterial pneumonia images, and 48 SARS images. Besides, pretrained networks were commonly used for the segmentation, feature extraction, and classification stages. To compare the infection regions segmentation performance, we consider the two state-of-the-art models U-Net and U-Net++. Lung regions were segmented by using 3d anisotropic hybrid network architecture (AH-Net), and the classification of segmented 3D lung regions was performed by using pretrained model DenseNet121. Therefore, we categorized the studies into four main tasks as follows: COVID-19/normal, COVID-19/non-COVID-19, COVID-19/non-COVID-19 pneumonia, and COVID-19 severity classification. In this study, we review the diagnosis of COVID-19 by using chest CT … The process is pretty fast and is employed at the point of care. However, in the middle of this difficult times many found 3d printing a helpful tool to fight the pandemic.  proposed another deep neural network model, namely, lesion-attention deep neural networks, where the backbone of the model used the weights of pretrained networks such as VGG16, ResNet18, and ResNet50. And results will be saved in ./Results/Lung infection segmentation/Semi-Inf-Net. which are used in the training process of pseudo-label generation. Please refer to the instructions in the main.m.

By March 11, 2020, the World Health Organization (WHO)  declared the new coronavirus called the COVID-19, a pandemic, and it has brought the entire globe into a compulsory lockdown. reported that the proposed system achieved the AUC score of 0.9791, sensitivity of 94.06%, and specificity of 95.47% for the external text cohort. Ori GitHub Link: https://github.com/HzFu/COVID19_imaging_AI_paper_list. Inf-Net: Automatic COVID-19 Lung Infection Segmentation from CT Images, IEEE TMI 2020. Some researchers classified COVID-19 cases using machine learning techniques instead of using deep learning approaches by extracting the features from the images and achieved high recognition results. He, X. Yang, S. Zhang et al., “Sample-efficient deep learning for covid-19 diagnosis based on ct scans,”. Instead of deep learning approaches, Barstugan et al.  proposed a model that was optimized by traditional CNN and VGG16 to stage the COVID-19 severity. Each study comprised one CT volume, one PET volume and fused PET and CT images: the CT resolution was 512 × 512 pixels at 1mm × 1mm, the PET resolution was 200 × 200 pixels at 4.07mm × 4.07mm, with a slice thickness and an interslice distance of 1mm. : accuracy; AUC: area under the curve; Ref.

Inf-Net: Automatic COVID-19 Lung Infection Segmentation from CT Images. from the COVID-19 CT Segmentation dataset  and 1600 unlabeled images from the COVID-19 CT Collection dataset . results, where neither GGO and consolidation infections can be accurately segmented.  performed another experiment to differentiate COVID-19 cases from other cases as bacterial pneumonia and SARS. Non-COVID-19 group includes either one of the cases which is not COVID-19 or a combination of all other cases. This has shown that widely used pretrained networks can be used very successfully at every stage of image classification. The data used to support the findings of this study are included within the article. ResNet, and However, while the images used are not standard and performing experiments on different image databases in each research does not make it possible to make a comprehensive comparison, it contributes to deduce general opinion.
