Investigation of Patient Dose Received During Digital Dental Radiography and Comparison with International Diagnostic Reference Level (DRL)

The utilization of radiation for health in Indonesia shows a significant increase, it can be seen from the increasing number of modalities of ionizing radiation sources used and the types of medical actions carried out with the help of radiation. The use of radiation must be monitored to ensure the protection and safety of workers, patients, and the community. In Government Regulation No. 33/2007 which regulates radiation safety for workers, the community and the environment, it can be seen that one of the protection requirements that must be met in the utilization of radiation is the optimization of radiation protection and safety. In diagnostic and interventional radiology, optimization can be interpreted as an attempt to make the dose received by patients as low as possible while maintaining optimum image quality. In this study, the effort to optimize patient dose is carried out on general radiography with the application of Si-INTAN (National Patient Dose Data Information System).

Abstract The International Electrotechnical Commission introduced the concepts of exposure index (EI), target exposure index (EIT) and deviation index (DI) to manage and optimize patient dose in real time. In this study, we have proposed an appropriate method for setting the EIT based on the Korean national diagnostic reference levels (DRLs). Furthermore, we evaluated the use of clinical EI, EIT and DI as tools for patient dose optimization in clinical environments by observing the changes in DI with those in EIT. According to the Korean national exposure conditions, we conducted experiments on three representative radiographic examinations (chest posterior–anterior, lateral and abdomen anterior–posterior) of clinical environments. As the exposure conditions and DRLs varied, the clinical EI, EIT and DI also varied. These results reveal that the clinical EI, EIT and DI can be used as tools for optimizing the patient dose if EIT is periodically and properly updated.
