WebThe dynamic range of the image obtained at 50 kV was 160 (i.e., L = 2.2), whereas the dynamic range of the image obtained at 125 kV was markedly reduced to 50 (i.e., L = 1.7). In radiology, it is generally true that high x-ray tube voltages (i.e., increased photon energies) reduce the dynamic range in radiographic images, and vice versa.
