Digital breast tomosynthesis

特許 係属中 Tomosynthesis, also digital tomosynthesis, is a method for performing high-resolution limited-angle tomography at mammographic dose levels. Digital breast tomosynthesis (DBT) can provide a higher diagnostic accuracy compared to conventional mammography. In DBT, like conventional mammography, compression is used to improve image quality and decreases radiation dose. The laminographic imaging technique dates back to the 1930s and belongs to the category of geometric or linear tomography
