Accurate and timely diagnosis of respiratory ailments like pneumonia, tuberculosis (TB), and COVID-19 is pivotal for effective patient care and public health interventions. Deep learning algorithms have emerged as potent tools in medical image classification, offering promise for automated diagnosis and screening. This study presents a deep learning-based approach for categorizing chest X-ray images into three classes: pneumonia, tuberculosis, and COVID-19. Utilizing convolutional neural networks (CNNs) as the primary architecture, owing to their ability to automatically extract relevant features from raw image data. The proposed model is trained on a sizable dataset of chest X-ray images annotated with ground truth labels for pneumonia, TB, and COVID-19. Extensive experiments are conducted to evaluate the model's performance in terms of classification accuracy, sensitivity, specificity, and area under the receiver operating characteristic curve (AUC-ROC). Additionally, we compare the performance of our deep learning model with traditional machine learning techniques, including support vector machines, decision trees, XGBoost, and evaluate its performance on an independent test set. Our findings demonstrate that the proposed deep learning model achieves high accuracy in classifying chest X-ray images of pneumonia, TB, and COVID-19, outperforming traditional methods and showing potential for clinical deployment as a screening tool, especially in resource-limited settings.
准确及时地诊断肺炎、肺结核(TB)和新冠肺炎等呼吸道疾病对于有效的患者护理和公共卫生干预至关重要。深度学习算法已成为医学图像分类中的强大工具,为自动诊断和筛查带来了希望。本研究提出了一种基于深度学习的方法,将胸部X光图像分为三类:肺炎、肺结核和新冠肺炎。利用卷积神经网络(CNN)作为主要架构,因为它们能够从原始图像数据中自动提取相关特征。所提出的模型在一个大型胸部X光图像数据集上进行训练,该数据集带有肺炎、肺结核和新冠肺炎的真实标签注释。进行了广泛的实验,以评估该模型在分类准确率、灵敏度、特异性和受试者工作特征曲线下面积(AUC-ROC)方面的性能。此外,我们将深度学习模型的性能与传统机器学习技术(包括支持向量机、决策树、XGBoost)进行比较,并在独立测试集上评估其性能。我们的研究结果表明,所提出的深度学习模型在对肺炎、肺结核和新冠肺炎的胸部X光图像进行分类时具有很高的准确率,优于传统方法,并显示出作为筛查工具在临床部署中的潜力,特别是在资源有限的环境中。
