| 内容記述 | Purpose:We aimed to evaluate the entrance skin dose (ESD) during radiofrequency catheter ablation (RFCA).M ethods:The X-ray fluoroscopic mode(70 kV, 7.5 p/s, 13.0× 13.0 cm)was evaluated at C-arm angles of 45°leftanterior oblique and 35°right anterior oblique. The bed height was raised by 4 to 8 cm from the bed base-pointposition (BP, 0 cm). Fluoroglass dosimeters were placed in three lines at 5-cm intervals on the surface of thephantom. The maximum skin dose conversion factors were calculated as the ratio of the calculated and the actualmaximum skin doses.Results:At heights of 6 and 8 cm,calculated ESDs had peak values of 93.0± 0.2 and 74.5± 2.7 mGy,respectively,whereas the actual maximum skin doses were in the range of 47.4± 0.2 to 59.5± 0.2 mGy. The maximum skin doseconversion factors were 0.79,0.87,0.53,0.64,and 0.72 at bed heights of 0,2,4,6,and 8 cm from the BP,respectively.Conclusion:A maximum skin dose conversion factor should be taken into consideration when determining themaximum skin dose in overlapping irradiation fields. | |||||
