With Digital Breast Tomosynthesis (DTB) the breast is squeezed and retained between the compression paddle and the detector, slightly similar as in digital mammography.

The x-ray tube moves in an arc overhead, executing a series of low-dose exposures at preset intervals, each from a different angle. The result is a series of projection images. The details of image acquisition unique to each system have been previously described in the literature.

A DBT system can acquire images in standard mammographic orientations (ie, craniocaudal, mediolateral oblique [MLO], and mediolateral). DBT can also be performed with spot compression and used to obtain implant-displaced views. DBT cannot be performed with magnification views.
