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 examination-level 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. •MammogramAnnotationTool enables free-form markup for mammography examinations.•The tool was developed together with radiologists to be easy to use.•The software allows for markup of benign and malignant findings.•Simultaneous side-by-side viewing of right and left mammograms is supported.•Necessary image processing features are supported.
