The purpose of this study was to calculate and compare the absorbed doses of properly and improperly collimated repeat examination exposures and to measure the anode heel effect to determine the difference in intensity between the cathode and anode ends of the x-ray beam. The investigators wanted to document the amount of additional radiation a patient receives due to improper collimation techniques and determine whether the difference in intensity between the anode and cathode ends of the x-ray beam was large enough to cause concern for increased patient absorbed doses for specific radiography examinations.
