Lung cancer has the highest death rate of any other cancer in the world. Detecting lung cancer early can increase a patient's survival rate. The corresponding work presents the method for improving the computer-aided detection (CAD) of nodules present in the lung area in computed tomography (CT) images. The main aim was to get an overview of the latest tools and technologies used: acquisition, storage, segmentation, classification, processing, and analysis of biomedical data. After the analysis, a model is proposed consisting of three main steps. In the first step, threshold values and component labeling of 3D components were used to segment the lung volume. In the second step, candidate nodules are identified and segmented with an optimal threshold value and rule-based trimming. It also selects 2D and 3D features from the candidate segmented node. In the final step, the selected features are used to train the SVM and classify the nodes and classify the non-nodes. To assess the performance of the proposed framework, experiments were performed on the LIDC data set. As a result, it was observed that the number of false positives in the nodule candidate was reduced to 4 FP per scan with a sensitivity of 95%.
肺癌是世界上所有癌症中死亡率最高的。早期发现肺癌可以提高患者的存活率。相关工作提出了一种改进计算机辅助检测(CAD)的方法,用于检测肺部 CT 图像中的结节。主要目的是概述最新使用的工具和技术:生物医学数据的获取、存储、分割、分类、处理和分析。经过分析,提出了一个由三个主要步骤组成的模型。在第一步中,使用阈值和三维组件的分量标记来分割肺体积。在第二步中,使用最优阈值和基于规则的修剪来识别和分割候选结节。它还从候选分割节点中选择 2D 和 3D 特征。在最后一步中,选择的特征用于训练 SVM 并对节点和非节点进行分类。为了评估所提出框架的性能,在 LIDC 数据集上进行了实验。结果表明,每个扫描的结节候选假阳性数量减少到 4 个 FP,灵敏度为 95%。
