Methodology for calculating average effective doses in radiography procedures as a tool for analyzing Form No. 3–DOZ

Form №3-DOZ is commonly used to analyze patient doses from radiographic procedures. However, direct comparison of average effective dose data from Form №3-DOZ with results of experimental studies is inappropriate, as Form №3-DOZ presents effective doses averaged over the patient's exposure projections. This leads to significant overor underestimation of the comparison results.

The aim of this study was to develop a method for estimating average effective doses per frontal or lateral projection for common radiographic procedures using Form №3-DOZ data.

Materials and Methods: The study was based on the data from the regional databanks of Form № 3-DOZ for Saint Petersburg and Leningrad regions; an original method for calculating average effective doses per projection has been developed.

Results and Discussion: average effective doses for the most common X-ray procedures performed on digital and analog X-ray units in St. Petersburg and the Leningrad Region in 2023 were determined.

Conclusion: It is advisable to integrate this method into software for completing Form №3-DOZ.
