| [ Summary ] |
The number of examinations using blood access interventional therapy (BAIVT) has increased recently. Because of more advanced and more complex procedures for BAIVT, longer treatment time is required. Therefore, it is important to determine exposure doses. The radiation exposure doses were measured for the patient and the operator. We measured the exposure dose using a thermoluminescence dosimeter (TLD). From the results, the patient skin dose was quite low with BAIVT compared to the other interventional radiology(IVR). The effective dose for the operator was also low, but the equivalent dose to the operator's fingers was high. Therefore, awareness should be focused on the exposure dose in the operator's fingers during BAIVT. In addition, we looked into the factors which affected exposure dose, and examined ways to reduce it. |
