| Abstract:: |
| Objective To evaluate the effective organ radiation dose in patients with conventional coronary angiography(CCA) and XperSwing coronary angiography. Methods The operating environment of CCA and XperSwing coronary angiography was simulated using the Chinese anthropomorphic chest phantom. The thermoluminescent dosimeters (TLDs) were placed on major organs of the phantomm. The organs' absorbed doses were measured and the dose-area products (DAPs) were recorded. The real effective dose was the summation of products of every organs' absorbed dose × a factor. The calculated effective doses was the product of the DAP × a factor. Results The average absorbed effective doses of XperSwing coronary angiography were lower than that of the CCA. The calculated effective doses of CCA and XperSwing coronary angiography were 3.88 mSv and 3.13 mSv, respectively, and less than the real ones (5.57 mSv, 4.94 mSv). Conclusions XperSwing coronary angiography would have less radiation dose than CCA does. The calculated effective dose would be less than the real one. |
