Sažetak
Aim: This work aims to point out the importance of establishing a system for image quality evaluation in conventional radiography.
Methods: The study was conducted retrospectively and it included image quality evaluation as well as analysis of imaging procedure. 20 radiographic images of pelvis were evaluated and the evaluation was carried out according to the European criteria for the quality of the radiographic images of pelvis. The imaging procedure was analysed using 3,651 radiographic images of the pelvis and 57,758 radiographic images of the chest. The analysis of the imaging procedure was carried out by comparing the used values with the recommended ones. The practice related to narrowing the X-ray beam to the area of interest using 50 radiological images of the chest was additionally analysed.
Results: Only one radiographic images of the pelvis were given the highest possible grade. Subjective evaluations of evaluators related to the selection of exposure parameters differed in the majority of evaluated pelvic images (80%). The X-ray tube voltages used during pelvic imaging were mostly in the recommended range but in case of imaging of chest X-ray tube voltage were lower than the recommended value in most cases. Pelvis were mostly imaged using X-ray tube source-to-detector distances that were within an acceptable range except for those patients who were standing during imaging. In the case of heart and lung imaging, these distances were generally in the acceptable range except in the case of supine patients when a larger number of patients were imaged using smaller distances. All 50 analysed radiological images of the chest were cropped.
Conclusions: The results of the analysis indicate the need to establish and implement a system for evaluating the quality of radiographic images, which would also include an analysis of the imaging procedure.
