Comparison of radiation doses of different machines in standard coronary angiography

Objective: To discuss the radiation dose contrast between heart special FD DSA machine and FD DSA machine in the standard 8 position coronary artery angiography. Methods: 50 cases were rearded with siemens AXIOM-Artisdfc heart FD DSA machine while the same samples with GE Tnnova IGS530 FD DSA machine. Todo stardard 8 position coronary artery angiography was done with 15 cm thick organic vireous die line measurement card for the two machines again. And then normal perspective and movie collection was done with 20 cm thick organic vitreous die line measurement card for the two machinesin referfnce point. At last the data was analyzed. Results: The value of cumulative dose for simens and GE were 153.7 mGy and 410 mGy respectively. The value of dpse-area product for simens and GE were 11.42 mGy * cm² and 37.22 mGy * cm² respectively. Conclusion: The radiation dose of the heart FD DSA machine was obviously less than that of the FD DSA machine. (authors)
