Abstract: (3 Views) |
Background: This study aims to measure the equivalent organ doses received by medical personnel during the coronary intervention procedure using Monte Carlo Geant4 Application for Tomographic Emission (GATE) simulation. Materials and Methods: The specific dimension of the angiography room was recorded from the Department of Diagnostic Radiology at Singapore General Hospital to generate the angiography room geometry in GATE. ICRP phantom was utilized to represent the medical personnel whereas MIRD phantom was used to represent the patient on the tabletop. Dose received by medical personnel were recorded at anterior posterior (AP) exposure projection at 73 kVp and 350 mAs for all the rooms. Results: The study revealed variations in the equivalent doses received by medical personnel across different room configurations. The highest dose variation was observed in the right and left lens, with the IR1 exhibiting the greatest exposure. Conclusion: This highlights the importance of using GATE simulation, as it enables accurate modeling of radiation scattering in various room setups, ensuring precise dose calculations. |
