Application of SR-Cu Radioprotector and Tube Current Modulation (TCM) to Reduce Radiation Dose in CT-Scan

Abstract

CT-Scan using high-dose X-ray radiation has harmful effects on the body or the environment if the utilization is not appropriate. One of the efforts to reduce radiation dose exposure to patients is to use a Silicone Rubber (SR)-Cooper (Cu) mixture as protection during examination. In addition to using composite materials, the mode selection in image capture on CT-Scan modalities can be chosen between Tube Current Modulation (TCM) with constant current. In this study, SR-Cu radioprotector was used for protection in thorax CT-Scan examination with TCM method and a constant current of 200 mAs and variation in Cu composition of 0%, 8%, 10%, and 12% of total radioprotector weight. The results showed that SR-Cu reduced the dose received by the patient by 4.86% while using TCM with SR-Cu reduced the dose by 39.24% compared to TCM without radioprotectors by 37.64%. From the research that has been done, it shows that the use of SR-Cu can increase radiation dose uptake.
