The light beam diaphragm can be used during the application of compression. This is to ensure the nipple is in profile, all breast is included in the main beam, both medial and lateral margins are included, no skin folds and an adequate breast compression.

The world of medical imaging in particular has benefited greatly from the use of physics. Ultrasound is sound waves that have a frequency above human audible. (Ultrasound Physics and Instrument 111). With a shorter wavelength than audible sound, these waves can be directed into a narrow beam that is used in imaging soft tissues.
