Implementing a quality assurance (QA) program facilitate a radio diagnostic machine in acquiring sufficient radiological information of superior quality while minimizing the radiation dose administered to the subject. Integral to this program is Quality Control (QC), which ensures quality through various measurements and procedures. The main objective of this study is to assess the compliance of private dental clinics operating dental X-ray machines in Riyadh with the QC requirements. Fifteen private dental clinics in different areas in Riyadh selected and examined in the study. QC tests performed on all different X-ray machines from different manufacturers. The QC tests were kV accuracy and reproducibility, exposure time accuracy and reproducibility, and beam quality in terms of Half-Value Layer (HVL). Of the surveyed devices, two did not pass all the criteria for QC requirements. The dental X-ray machine that did not pass i.e. failed exclusively in kV accuracy but passed all the remaining QC tests. Particularly the exposure time reproducibility and Kilovoltage Accuracy. It is essential to establish a QC program in private dental clinics operating radiation-producing machines such as dental X-ray machines as it is important to ensure their compliance with the national standards for radiation safety.

As X-ray applications continue to evolve across medical disciplines, meticulous implementation of Quality Assurance (QA) protocols becomes paramount. It is the cornerstones in X-ray applications, ensuring accuracy, safety and effectiveness of diagnostic procedures. To get optimum use of medical equipment, specific performance tests must take place. The aim of this work is was to evaluate the performance of GE conventional X-ray System installed in 2007 at Radiological Science Department of King Saud University. Non-invasive auto meter used to evaluate the performance of such X-ray imaging system. The study investigates various Quality Control (QC) parameters, including milliampere-seconds (mAs) linearity, tube voltage accuracy, and exposure time reproducibility, to ensure compliance with established standards. All QC tests have done according to the intentional standard reports (AAPM No. 74) and National recommendations of King Abdullah City for Atomic & Renewable Energy. The obtained results indicate that the X-ray unit demonstrates acceptable mAs linearity, tube voltage accuracy, reproducibility and exposure time reproducibility tests and thus ensuring consistent X-ray output. All the obtained results meet the international standards. In general, the Department of Radiological Sciences adheres to strict quality control and quality assurance protocols for the department's equipment. To maintain consistency in radiation output, ensure user safety, and improve image quality in radiography. Through continuous monitoring and evaluation of equipment performance, while minimizing unnecessary radiation exposure to users.
