First data on quality control test done in diagnostic X-ray facility at major public hospitals in Kathmandu valley, Nepal

Abstract

One of the most important goals of good medical practice in the use of X-ray is to diagnose the disease and its extent to minimize an adverse effect. During any action taken in diagnostic X-ray, there is an important issue of quality of the image and dose to the patient. Hence, regular practice of quality control in diagnostic X-ray is essential to provide a good quality images and less hazard to the patients and its checking on regular basis enhances the appropriate diagnosis with minimum side effects. The quality control tests were carried out at thirteen X-ray units at seven different government hospitals in Kathmandu valley. The parameter like kV, kVp, dose, dose rate, HVL and mAs were measured with the acceptance limits. In this study, beam alignment test, radiation leakage test and focal spot test were also done. During the study, we found that there is not any established proper method for the installment of diagnostic X-ray equipment and acceptance testing procedure in Nepal. Actions were not taken to improve the old X-ray machine and for restoring it to a proper working condition. The study shows that the need for quality assurance of diagnostic X-ray to be taken to avert detrimental effects to patients and staffs. Radiographers should provide sufficient training to ensure proper condition of X-ray machine. Radiation regulation now is essential for such programs to be introduced. Any program to manage patient dose in radiology should provide a high priority in the country like Nepal. Dose given in diagnostic X-ray should be compared with standard reference level on regular basis to identify the condition of the X-ray. Institute must introduce a mandatory system for acceptance test of X-ray when installed and regular quality control program.
