A High-Kilovolt (KV) Technique Is Necessary in CT Imaging for All

A high-kilovolt (kV) technique is necessary in CT imaging for all of the following reasons except:

A) to reduce the contrast of bone relative to soft tissues.
B) to increase the probability of beam hardening.
C) to reduce the dependence of attenuation coefficients on photon energy.
D) to produce a high-radiation flux at the detector.
