Detailed explanation-5: -Breast tomosynthesis, also called three-dimensional (3-D) mammography and digital breast tomosynthesis (DBT), is an advanced form of breast imaging, or mammography, that uses a low-dose x-ray system and computer reconstructions to create three-dimensional images of the breasts.
