                                                            ABSTRACT

Various researchers who have carried out national and international surveys have reported wide variations in patient dose arising from specific x-ray examinations. This study aims to measure and evaluate the average entrance surface dose associated with Pelvic X-Ray Examinations and help in determining the appropriate exposure factors for optimal image quality while ensuring patient safety from radiation hazards. A cross-sectional, retrospective study was conducted with a sample size of 50 adult and geriatric patients who underwent pelvic x-ray examinations at the radiology department of the University of Calabar Teaching Hospital between October 2022 and February 2023. Data was collected using a direct digital x-ray machine and automatic dose calculation software, and analyzed using descriptive statistics and inferential statistics.The study found that the average entrance surface dose used was 7.8591mGy, with an exposure factor range of 60-80kVp and 8.10-400mAs. kVp was not a strong positive indicator of the entrance surface dose, as image processing techniques such as edge enhancement and contrast enhancement can increase the dose. 80% of the patients exceeded the recommended entrance surface dose level of 3.6mGy for an adult undergoing pelvic x-ray examination using the digital x-ray machine. The neglect of appropriate exposure factors by radiographers may lead to patient overexposure, as dependence on image editing software can result in intentional or unintentional radiation dose increase to compensate for poor exposure settings. The study recommends further evaluation of entrance surface dose and comparison with international diagnostic reference levels to promote and maintain patient safety and protection from radiation hazards.
