It is a specialized form of mammography that uses digital receptors and computers instead of the usual X-ray film to help examine breast tissue. It is an X-ray examination of the breast done digitally.
Just like Digital photography, Digital Mammography works the same, but it uses X-radiation like digital X-ray. Your breast will be placed on the image receptor and pressed accordingly to cover all breast areas. It is routinely done in both breasts with different angulations.
