Abstract:

This report covers the approach, procedures and techniques employed in evaluating and comparing the speed, contrast, quality and handling characteristics of three different x-ray film types from each of three different manufacturers. Included are details on the fabrication and calibration of aluminum step-tablets used in the evaluations and comparisons. Calibration curves for four different kilovoltages, characteristic film curves for each of the films evaluated, and tables of relative film speed and contrast are presented. Subjective evaluation of each of the films for quality and handling characteristics is also presented. The effort of this project was limited to the range of 50 to 140 kilovolts with aluminum as the absorber however, techniques and methods used could be extended to other energies and materials.
