End-to-End Breast Mass Classification on Digital Breast Tomosynthesis

no code implementations MIDL 2019 Chao Zheng, Tianlan Mo

Automatic classification of the masses in digital breast tomosynthesis(DBT) is still a big challenge and play a crucial role to assist radiologists for accurate diagnosis. In this paper, we develop a End-to-End multi-scale multi-level features fusion Network (EMMFFN) model for breast mass classication using DBT.
