Question 1

kVp (kilovolt peak)

Answer 1

The maximum voltage applied across the x-ray tube. Determines the kinetic energy of the electrons and therefore the highest energy in the x-ray beam. Determines the quality and penetrating ability of the x-ray beam. Influences the radiographic contrast (degree of difference between black and white on a radiograph). 1 kilovolt = 1000 volts.

kVp= Grey scale

Question 2

Answer 2

Dorsal curvature of the spine.
