论文摘要
在过去的两年中，世界遭受了Covid-19（SARS-COV-2）的困扰，造成了人们的日常生活造成的损害和变化。因此，使用深度学习对胸部计算机断层扫描（CT）扫描进行了深入学习的自动检测变得很有希望，这有助于有效纠正诊断。最近，提出了基于变压器的COVID-19检测方法在CT体积中使用3D信息。但是，其选择切片的采样方法并不是最佳的。为了利用CT体积中的丰富3D信息，我们使用新型的数据策展和适应性采样方法提出了基于变压器的COVID-19检测，并使用灰度级别共发生矩阵（GLCM）提出了一个基于变压器的COVID-19。为了训练由CNN层组成的模型，然后是变压器体系结构，我们首先基于肺部分割执行数据策划，并利用CT卷中每个切片的GLCM值的熵来为预测选择重要切片。实验结果表明，所提出的方法以较大的边缘改善了检测性能，而不会对模型进行太多的修改。
The world has suffered from COVID-19 (SARS-CoV-2) for the last two years, causing much damage and change in people's daily lives. Thus, automated detection of COVID-19 utilizing deep learning on chest computed tomography (CT) scans became promising, which helps correct diagnosis efficiently. Recently, transformer-based COVID-19 detection method on CT is proposed to utilize 3D information in CT volume. However, its sampling method for selecting slices is not optimal. To leverage rich 3D information in CT volume, we propose a transformer-based COVID-19 detection using a novel data curation and adaptive sampling method using gray level co-occurrence matrices (GLCM). To train the model which consists of CNN layer, followed by transformer architecture, we first executed data curation based on lung segmentation and utilized the entropy of GLCM value of every slice in CT volumes to select important slices for the prediction. The experimental results show that the proposed method improve the detection performance with large margin without much difficult modification to the model.
