Abstract:
Objective to compare the calculated effective radiation dose variations in cardiac interventional procedures of coronary angiography (CAG) and percutaneous transluminal coronary angioplasty (PCI) by using the different tissue weighting factors recommended by ICRP Publication 60 with that recommended by ICRP Publication 103. Methods Measurements of organ doses were carried out with an anthropomorphic phantom equipped with thermoluminecent dosimetry. The effective radiation doses were separately calculated using the tissue weighting factors provided by ICRP 60 and provided by ICRP 103, and the results obtained from ICRP 60 were compared with that obtained from ICRP 103. Conversion factors of effective, radiation dose to dose area product (DAP) were also calculated according to different publication.Results The variations in the effective dose were 6.88% for CAG and 8.46% for PCI. The effective dose variations in CAG and PCI were. 7.25% and 8.76% for female and were 6.51% and 8.17% for male,respectively. The effective conversion factors of DAP were. 0.10 ～ 0.11 and 0.13 ～ 0.14 for CAG and PCI,respectively, according to ICRP 60 and 103. Conclusion The variation of conversion factors of effective dose indicates that in making estimation of effective radiation dose. by using the widely accepted conversion factors, the adjustment of organ weighting factors recommended by ICRP 103 should be considered.
