Abstract

In this article, a study of various medical imaging modalities and survey of computer aided detection (CAD) approaches used for the detection of breast cancer are presented. Early breast cancer detection, is important as it can increase the rate of diagnosis, cure and survival of the affected women. Medical imaging techniques can detect early signs of breast cancer. They are also used to diagnose, stage breast cancer and guide treatments. This article explains the imaging procedure, analysis of images, benefits and limitations of standard medical imaging techniques such as mammography, ultrasound, magnetic resonance imaging, and thermography. Also some of modern imaging techniques are discussed here. Comparative study of mammography, ultrasound, thermography and magnetic resonance imaging describes the benefits of thermography in early detection of breast cancer. CAD provides a fast, reliable, and cost-effective second opinion to support doctors with the diagnostic management of breast cancer. This article reviews various CAD algorithms developed and studied for mammography, ultrasound and thermography. From the literature review, it is observed that accuracy of detection of breast abnormalities using CAD are decided by many factors, such as size of database, image quality, segmentation of region of interest, extracted features and classifiers used, etc.
医学成像技术和计算机辅助诊断方法用于检测乳腺癌,重点是热成像-综述
在这篇文章中,各种医学成像模式的研究和调查的计算机辅助检测(CAD)方法用于乳腺癌的检测提出。乳腺癌的早期检测非常重要,因为它可以提高受影响妇女的诊断率、治愈率和生存率。医学成像技术可以发现乳腺癌的早期迹象。它们也被用于诊断、分期乳腺癌和指导治疗。本文解释了成像程序、图像分析、标准医学成像技术(如乳房x线摄影、超声、磁共振成像和热成像)的优点和局限性。本文还讨论了一些现代成像技术。乳房x线摄影、超声、热成像和磁共振成像的比较研究描述了热成像在乳腺癌早期检测中的益处。CAD提供了一个快速、可靠、经济的第二意见来支持医生对乳腺癌的诊断管理。本文回顾了各种CAD算法的发展和研究乳房x线摄影,超声和热成像。从文献综述中可以看出,使用CAD检测乳腺异常的准确性受多种因素的影响,如数据库的大小、图像质量、感兴趣区域的分割、提取的特征和使用的分类器等。
