In this study, we quantitatively analyzed radiation exposure to a fetus during interventional cardiology (IC) procedures. Monte Carlo simulation was performed using the radiation transport code MCNPX2.7.0 to model a scenario of exposure during a coronary angiography procedure. The pregnant patient was represented by the computational anthropomorphic phantom, Katja. The X-ray tube was represented by a point source emitting a pyramidal photon beam towards the patient's heart, under three projections, PA (posteroanterior), LAO90 (left anterior oblique, 90°), and LAO45 (left anterior oblique, 45°). The applied voltage to the X-ray tube was 75 kV, and the total filtration was 3.5 mmAl. The mean effective dose conversion coefficients for the three projections were 0.22  \(\text{mSv}/\text{Gy} \cdot \text{cm}^{2}\) , consistent with calculated or experimental data from the literature.

摘要

In this study, we quantitatively analyzed radiation exposure to a fetus during interventional cardiology (IC) procedures. Monte Carlo simulation was performed using the radiation transport code MCNPX2.7.0 to model a scenario of exposure during a coronary angiography procedure. The pregnant patient was represented by the computational anthropomorphic phantom, Katja. The X-ray tube was represented by a point source emitting a pyramidal photon beam towards the patient's heart, under three projections, PA (posteroanterior), LAO90 (left anterior oblique, 90°), and LAO45 (left anterior oblique, 45°). The applied voltage to the X-ray tube was 75 kV, and the total filtration was 3.5 mmAl. The mean effective dose conversion coefficients for the three projections were 0.22  \(\text{mSv}/\text{Gy} \cdot \text{cm}^{2}\) , consistent with calculated or experimental data from the literature.
