Breast cancer is a female malignant tumor with high incidence
and early diagnosis is extremely important. Over the past years
the two-dimensional imaging technology has been an important tool for breast cancer screening and diagnosis. However
more and more non-typical image features are confirmed
and two-dimensional imaging has shown many deficiencies. The application of new three-dimensional imaging technology can provide richer diagnostic information than two-dimensional imaging technology. This paper reviews the progress of three-dimensional imaging of breast tumors.
