Penentuan Diagnostic Reference Level Pesawat Fluoroskopi C-Arm Pada Simulasi Brakhiterapi

The brachytherapy simulation process was carried out using a C-Arm fluoroscopy. One of the efforts to optimize the radiation dose received by the patient during the examination is to determine the value of the Diagnostic Reference Level (DRL). In this study, the determination of the DRL value, especially in gynecological cases, was based on the type of applicator used in the simulation process, namely: the silinder applicator, the ovoid applicator, and the fletcher applicator. The results show that the greatest average radiation value is the fletcher applicator, after that the ovoid applicator, and the smallest is the silinder applicator. The DRL value also shows the same results, namely 8,0 mGy (cylinder applicator), 9,2 mGy (ovoid applicator), and 9,5 mGy (fletcher applicator). The DRL is used as a local DRL as an initial guide for dosage values. It is hoped that from this reference value, further optimization can be carried out, so that the minimum dose received by the patient does not exceed the DRL, or we can even look for other optimization efforts so that the radiation dose received can be smaller, or even when there are patients who receive excessive radiation doses. Then further investigations can be carried out to find out the cause of this and the solution for handling it. And of course, periodically re-analyze the DRL value, so that the value is always relevant.
