Assessment of patient dose in routine digital radiography in Iran

Background: The present study aimed to investgate patent dose in common X-ray examinatons to estmate effectve dose in the digital radiography in Iran. Materials and Methods: Entrance surface dose (ESD) was measured based on applied exposure parameters for the common actual examinaton; and then effectve dose (ED) was calculated by use of PCXMC software. The study was conducted on 15358 patents in 85 X-ray rooms; and the necessary data was collected for five age groups, 0-1 year, 1-5 years, 5-10 years, 10-15 years old and adults in each projecton. Results: The ranges of ESD and ED in different examinatons for all the age groups are 0.02-10.20 mGy and 2.42-378.96 μSv respectvely. Conclusion: The effectve dose as criteria can be used to reduce patents' doses. The special consideratons such as: adequate training of imaging staff; updatng clinical audits; patent dose consideratons; implementaton of systematc and regular quality assurance and quality control programs in medical imaging departments should be taken into account to optmize radiological practces. © 2020 Novin Medical Radiation Institute.
