Principles of radiographic exposure a new approach.
Radiographic technique charts have traditionally been established by the empirical method. A precisely calculated chart based on the effective energy of the spectrum and the output of the equipment will give more consistent results of density and contrast as well as repeatability of these results from patient to patient. A better understanding of patient attenuation and screen energy sensitivity will enable the radiographer to logically adjust technical factors to change density or contrast scales as required.
