In normal digital two-dimensional mammography, a two-dimensional image of a three-dimensional object (the breast) is obtained, with the images of the tissues overlapping. With the Digital Tomosynthesis technology in mammography developed in recent years, breast tissue can be scanned in 3D. With this method, a large number of images are taken at different angles and a 3-dimensional image of the breast tissue in one mm sections is obtained with the computer system, just like in computed tomography.
