摘要:

在SARS-CoV-2(COVID-19)感染的全球传播中,早期检测该疾病至关重要,尤其是在这种流行病的热点地区。全球有超过1.1亿例感染病例。由于其快速性和有效的结果,计算机断层扫描(CT)扫描图像是首选的逆转录聚合酶链反应(RT-PCR)。及早发现和隔离病人是控制疾病传播的唯一可能办法。CT扫描的自动分析可以在此过程中提供巨大的支持。在这篇文章中,我们提出了一种新的方法来检测SARS-CoV-2使用CT扫描图像。我们的方法是基于一个非常直观和自然的想法,分析形状,试图模仿专业医生。我们主要通过量化SARS-CoV-2的拓扑特性来追踪其特征。我们主要使用拓扑数据分析(TDA)中的持久同源性工具来计算这些拓扑性质。我们在“SARS-CoV-2 CT扫描数据集”\citep{soares2020sars}上对我们的模型进行了训练和测试,这是一个开源数据集,包含2,481个正常和COVID-19患者的CT扫描。我们的模型产生了总体基准F1分数$99.42\% $、准确度$99.416\%$、精确度$99.41\%$和召回度$99.42\%$。TDA技术具有巨大潜力,可用于有效和迅速检测COVID-19。TDA的巨大潜力可以在全球诊所中用于快速和安全地检测COVID-19,特别是在RT-PCR实验室和/或试剂盒处于严重危机的低收入和中等收入国家。

英文摘要:

In this worldwide spread of SARS-CoV-2 (COVID-19) infection, it is of utmost importance to detect the disease at an early stage especially in the hot spots of this epidemic. There are more than 110 Million infected cases on the globe, sofar. Due to its promptness and effective results computed tomography (CT)-scan image is preferred to the reverse-transcription polymerase chain reaction (RT-PCR). Early detection and isolation of the patient is the only possible way of controlling the spread of the disease. Automated analysis of CT-Scans can provide enormous support in this process. In this article, We propose a novel approach to detect SARS-CoV-2 using CT-scan images. Our method is based on a very intuitive and natural idea of analyzing shapes, an attempt to mimic a professional medic. We mainly trace SARS-CoV-2 features by quantifying their topological properties. We primarily use a tool called persistent homology, from Topological Data Analysis (TDA), to compute these topological properties. We train and test our model on the "SARS-CoV-2 CT-scan dataset" \citep{soares2020sars}, an open-source dataset, containing 2,481 CT-scans of normal and COVID-19 patients. Our model yielded an overall benchmark F1 score of $99.42\% $, accuracy $99.416\%$, precision $99.41\%$, and recall $99.42\%$. The TDA techniques have great potential that can be utilized for efficient and prompt detection of COVID-19. The immense potential of TDA may be exploited in clinics for rapid and safe detection of COVID-19 globally, in particular in the low and middle-income countries where RT-PCR labs and/or kits are in a serious crisis.
