BCSDBT-Seg Lesion Segmentation Annotations and Structured BI-RADS Reports for Breast Tomosynthesis Dataset

Abstract

Digital breast tomosynthesis (DBT) is an established imaging modality for breast cancer screening that reduces tissue overlap compared with conventional digital mammography. Publicly available DBT datasets remain scarce, and existing resources predominantly provide coarse image-level labels or 2D bounding boxes.
