| Abstract:: |
| Objective To determine the distribution of irradiation dose in X-ray room with different radiation directions in cerebral angiography operations. Methods The Model 451B air ionization chamber survey meter was used to measure the irradiation dose distribution in the X-ray room when cerebral angiographies were performed at high kV and high dose. The doses were measured within 3 m when the phantom was irradiated in posterior-anterior (PA) position, anterior-posterior(AP) position, right anterior oblique (RAO) 30?, left anterior oblique (LAO) 30?, right-lateral (RL) position, and left-lateral(LL) position, respectively. Results Both the relative data and the distribution curves of the six radiation directions were obtained by using the same interventional operation model. The irradiation dose to the primary operator was minimal in P-A and RL positions,at 0.4 mGy/h, and was maximal in LL position, at up to 1.54 mGy/h. Furthermore, the lowest irradiation dose level was found to be lower than 10 μGy/h at the side of the framework field. Conclusions Low-irradiation position and rational work place were proposed to reduce the operators’ absorption dose during interventional radiology procedures. |
