영문 초록

The International Electrotechnical Commission (IEC) 62494-1 has defined the exposure index (EI) that have a proportional relationship with the dose incident on the image receptor, and target exposure index (EIT), deviation index (DI). In this study, an appropriate EIT for skull radiography was established through the diagnostic reference level (DRL) and changes in DI were confirmed. Entrance surface dose (ESD) and EI were obtained using the computed radiography system displayed the EI as per IEC on console and skull phantom by experiment based on the national average exposure conditions announced in 2012 and 2019. And appropriate EIT was established by applying the DRL in 2012 and 2019. As a results, the EIT is changed according to the change in the DRL, and the exposure condition that becomes the ideal DI according to the change in the EIT also has a difference of about 1.41 times. DRL is recommended to optimize the patient dose, however it is difficult to measure in real time at medical institutions whereas EI and DI are displayed on the console at the same time as exposure. When the EIT is set based on the DRL and the DI is closed to an ideal value, it is useful as a patient dose management tool. Therefore, when the EIT is periodically managed along with the revision of the DRLs, the patient dose can be optimized through the EI, EIT and DI.
