Editor’s Note: Part one appeared in June: “Variances and Human Factors in Radiographic Image Interpretation.”
Radiographic testing (RT) techniques should be developed to achieve the highest image quality level achievable. The choices of energy/source and film imaging plates and processing should be made accordingly. Probability of Detection (POD) analysis cannot be applied effectively where the quality level is marginal or unacceptable due to improper techniques, which many times are used to increase productivity. We have experienced many questionable RT images produced by the “trial and error” technique rather than by scientifically developing the optimum technique. When image quality is found to be unsatisfactory, it is critical for the RTFI to require that the radiographer retake exposures to produce images of an acceptable quality to allow proper interpretation.
