Qualitative and Quantitative Evaluation of Breast Images-Comparative Study of Mammogram and Thermogram
International Journal of Systems Applications, Engineering & Development
The early detection of breast cancer can lower the risk of mortality among women. Mammography has been considered as standard tool for screening breast cancer today. Despite its ability in detecting breast condition, mammography has some drawbacks. Mammography technique is less effective for younger patients and it is not suitable for women with dense breasts. Thermography is being proposed as adjunct screening tool for breast cancer detection. Breast infrared thermography is a noninvasive
... dure suitable for all age groups and does not involve any exposure of radiation. Hence the proposed study focused on feature extraction in breast thermograms for detecting breast cancer and compared with mammogram results to show that even breast thermography gives a significant difference between normal and abnormal patterns of breast images. The thermography can be used as a complimentary tool together with mammography to enhance its efficiency in detecting breast cancer, but it cannot substitute mammography completely. The texture features such asskewness, kurtosis, cluster prominence, entropy and coarsenesswere extracted from thermogram and mammogram images and analysis were done. The aim of the present study was to compare the results of normal and malignant subjects using mammogram and thermogram modalities. The obtained results show the significant difference among the features extracted to classify normal and abnormal images.
