Abstract

Breast cancer is a leading cause of death nowadays in women throughout the world. In developed countries, it is the most common type of cancer in women, and it is the second or third most common malignancy in developing countries. The cancer incidence is gradually increasing and remains a significant public health concern. The limitations of mammography as a screening and diagnostic modality, especially in young women with dense breasts, necessitated the development of novel and more effective strategies with high sensitivity and specificity. Thermal imaging (thermography) is a noninvasive imaging procedure used to record the thermal patterns using Infrared (IR) camera. The aim of this study is to evaluate the feasibility of using thermal imaging as a potential tool for detecting breast cancer. In this work, we have used 50 IR breast images (25 normal and 25 cancerous) collected from Singapore General Hospital, Singapore. Texture features were extracted from co-occurrence matrix and run length matrix. Subsequently, these features were fed to the Support Vector Machine (SVM) classifier for automatic classification of normal and malignant breast conditions. Our proposed system gave an accuracy of 88.10%, sensitivity and specificity of 85.71% and 90.48% respectively.

摘要

乳腺癌是当今全球女性死亡的主要原因。在发达国家,乳腺癌是女性最常见的癌症类型,在发展中国家是第二或第三最常见的恶性肿瘤。癌症发病率逐渐上升,仍然是一个重大的公共卫生关注点。乳腺摄影作为一种筛查和诊断方式存在局限性,特别是在乳腺致密的年轻女性中,因此需要开发具有高灵敏度和特异性的新型且更有效的策略。热成像(热图)是一种非侵入性的成像程序,用于使用红外(IR)相机记录热模式。本研究旨在评估热成像作为检测乳腺癌的潜在工具的可行性。在这项工作中,我们使用了从新加坡综合医院收集的 50 张 IR 乳房图像(25 张正常和 25 张癌症)。从共生矩阵和运行长度矩阵中提取纹理特征。随后,将这些特征输入支持向量机(SVM)分类器,以自动分类正常和恶性乳房状况。我们提出的系统的准确率为 88.10%,灵敏度和特异性分别为 85.71%和 90.48%。
