TLDR
The imaging procedure, analysis of images, benefits and limitations of standard medical imaging techniques such as mammography, ultrasound, magnetic resonance imaging, and thermography, and some of modern imaging techniques are discussed here.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.read more

Detection of Breast Cancer Thermograms based on Asymmetry Analysis using Texture features
TL;DR: Images are extracted from the temperature matrix, dataset available at DMR visual labs and the texture features based on different gray levels are extracted and the variation in temperature for the left and right breast is observed on the basis of asymmetry analysis.

Comparative Analysis of Medical Imaging Techniques Used for the Detection of Thyroid Gland with an Emphasis on Thermogram
TL;DR: A comparative study of various medical imaging techniques explains the Thermogram image is the noninvasive system that detects the relative temperature variations in patients form thyroid diseases as discussed by the authors , and it is observed that detection of thyroid abnormalities using different techniques not only decides many factors such as segmentation of the region of thyroid gland, image quality, and extraction features and classifiers.
