Investigating the effect of image quality assurance programs on radiographic imaging performance

Abstract

The study was carried out to assess the effect of image quality assurance programs on radiographic imaging performance. The general objective of this study was to investigate the effect of image quality assurance (QA) programs on radiographic imaging performance. The specific objectives were. To conduct visual inspection on x-ray equipment, processing and radiographic images pre and post implementation of quality assurance programs. To access the different quality control tests performed on the x-ray imaging equipment and to find out if quality assurance programs are being implemented. The key findings of the research included the following: The implementation of QA programs has a positive impact on the overall condition of radiographic equipment and the quality of the produced images. As evidenced by the high mean scores for equipment reliability (4.3) and image clarity (4.2), regular visual inspections both before and after QA program implementation appear to contribute to improved maintenance and performance. Components such as regular equipment maintenance, radiation dose monitoring, and image quality assessment were among the most frequently reported. The presence of these QC tests supports the notion that systematic evaluation through both technical assessments and visual inspections is critical in ensuring the optimal functioning of X-ray equipment. Finally, 85% of the facilities have a formal QA program in place. This high percentage indicates that the concept of QA is well-acknowledged in radiographic departments. However, challenges such as inadequate staff training (reported by 40% of respondents) and limited resources (30%) suggest that while QA programs exist, their effective implementation may be hindered by operational constraints. The variation in the duration of QA program implementation from newly established programs (less than 1 year) to those in place for more than 6 years also points to differences in experience and possibly in the maturity of the QA processes across departments. The following are some of the recommendations drawn from the study: Standardize Visual Inspection Protocols, Training and Skill, Regular and Comprehensive Testing, Develop a schedule for regular QC tests that include equipment maintenance, Upgrade Testing Equipment, Expand QA Program Adoption, Address Training and Resource Gaps and Enhance Communication.
