text: In general, extremity imaging may be performed at table top because two factors help to reduce the amount of scatter: (a) thin body parts are easier to penetrate and therefore permit the use of lower x-ray tube voltages (kV); (b) the presence of bone (high Z) means that most interactions are photoelectric (not Compton) and thus scatter is reduced.
