| Abstract:: |
| Objective To compare radiation doses to patients between rotational angiography and standard angiography.Methods According to different modes, our experiment was divided into RA (Dual-axis Rotational Angiography) group and SA (Standard Angiography)group. The latter was divided into 3 subgroups (SA1, SA2 and SA3) in terms of different time of cine. The procedure time and the position were controlled by the order preset into the machine. Each group consisted of 10 repeated operations with a unique phantom to simulate the true patients. The radiation doses were measured by using dose meter provided by the machine and TLD system; the means of the data were compared. Results The mean of total accumulated DAP and AK in group RA were 3 061.6 mGy·cm2 and 64.2 mGy, respectively, compared with group SA1 (4 213.9 mGy·cm2 and 85.5 mGy), SA2 (6 436.0 mGy·cm2 and 112.2 mGy), SA3 (12 810.4 mGy·cm2 and 243.7 mGy). The mean of accumulated dose in group RA was 37.70 mGy, higher than group SA1 (26.56 mGy) but lower than group SA2 (46.86 mGy) and SA3 (77.79 mGy). The gap between highest dose and lowest dose in RA group was insignificant whereas significant in the subgroups of SA. Conclusions In comparison with conventional angiography, the dual-axis rotational angiography has the potential to reduce radiation exposure of patients significantly so as to prevent skin radiation injures. |
