Objectives: X-ray exposure in medicine is considered to be the major part in man-made radiation. The purpose of this study was to survey the effect of optimization in image quality and entrance skin dose for patients in radiographic examinations.

 Methods:  In this survey, seven radiographic examinations were studied. First, patient dose of radiation was measured and the quality of the radiography images was considered. Also, the number and causes of rejected films were checked. Then, corrective action of the European Commission (EC) was implemented and quality control of radiology equipment was performed. Once more, patient radiation dose, quality of radiographic images and number and cause of rejected films were analysed.

Results: The image quality was not convenient before corrective actions. With implementation of the corrective actions, the quality of radiographic images was increased so that it was statically significant. Total rejections in all types of radiographies were 18.33% and 11.17%, respectively, before and after improvements. Entrance Skin Dose for patients was 1.59 mGy before improvements and 1.21 mGy after improvements.

Conclusion: The result of this survey demonstrated that it’s possible to implement a program for coordination of protection optimization in general radiology. After implementing the corrective actions for optimization of protection, the radiation dose decreased with clinically acceptable images as well as with the number of rejected films. This decreased dose can reduce cumulative dose, which reduces probability of cancer risk and genetic effects in society.

Keywords: Radiological examination, Entrance skin dose, Image quality, Rejected film, P-value
