Dose Monitoring System in an Effort to Improve the Quality of Diagnostic and Interventional Radiology Services

Abstract

X-ray-based medical imaging has become one of the most popular imaging modalities today. Computed tomography (CT) and interventional procedures can result in higher radiation exposure for patients compared to other radiographic examinations. There has been an increase in the effective dose of > 100 mSv from some procedures. Recent studies have shown that multiphase CT imaging and repeated imaging provide larger radiation doses in some patients. In considering the effective dose (E) for each patient, it is essential to note that the risk per Sv tends to be greater on average in pediatric patients than in adults. In addition, E can be used to describe the possible risk to the patient. Dose management is essential in monitoring and controlling patient doses. Consistent and systematic monitoring of radiation dose is needed to improve the quality of diagnostic and interventional radiology services. Dose monitoring activities include performance control, optimization of protocols used, corrective actions against non-standard practices, and raising awareness for radiation workers to minimize risks. The use of a dose monitoring system (Dose Monitoring System) responds to concerns about the radiation risk that comes from diagnostic imaging modalities, particularly Computed Tomography (CT) and fluoroscopy in interventional procedures. The dose monitoring system (Dose Monitoring System) has developed into a requirement in monitoring and controlling patient doses and is one of the applications of radiation safety culture that can improve diagnostic and interventional radiology services.
