On Using Image Processing Techniques for Evaluation of Mammography Acquisition Errors
Abstract
Mammography is an extremely important examination considering the high incidence of breast-related diseases, since it helps to detect several abnormalities. Errors in the acquisition can mask potential problems. The objective of this study is to apply image processing techniques for automated detection of some very common errors. Craniocaudal (CC) and mediolateral oblique (MLO) mammograms views were evaluated considering aspects as: (1) breast symmetric positioning, (2) adequate nipples profiling and centering, and (3) properly pectoral muscle location. The image processing techniques used are based on: skeletonization, Hough transform and thresholding. The achieved results are impressive especially in the determination of the nipple position.
