WebkVp. HIGH kVp will result in images with WIDE latitude. Different films have different latitudes H and D Curve. As the curve increases, the density increases. The sharper the angulation of the curve, the less the latitude of the film and the greater the contrast. The flatter the angulation, WebIn 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.
