MammogramAnnotationTool: Markup tool for breast tissue abnormality annotation

In this work, we present an open-source MATLAB software tool for mammography image annotation. The tool has an easy-to-use graphical user interface enabling simultaneous visualization of both breasts. Annotations can be assigned to six categories for abnormal breast tissue: malignant mass, benign mass, malignant calcification, benign calcification, malignant architectural distortion, benign architectural distortion. Furthermore, characterization details, such as, morphology of the abnormality, can be assigned to each annotation. Optional examinationlevel breast density assessment can also be specified. This tool has been successfully applied as part of the data collection pipeline in already published deep learning-based segmentation and classification studies.
