A follow-up study of a third-party radiographic evaluation system.
A follow-up study was conducted to evaluate the performance of the rating system for third-party carriers which was developed and instituted in 1976. Further, the technical quality of radiographs submitted under the system was evaluated. The conditions and parameters of the second study were identical to those of the original work. Statistical comparison of the data from both studies shows a significant decrease in the frequency of error occurrences over the 3-year span between the studies.
