Monte Carlo study of patient and medical staff radiation exposures during interventional cardiology

The aim of this study is to assess the radiation exposure patient and medical staff during interventional cardiology procedures. Realistic scenarios were developed using adult reference anthropomorphic phantoms adopted by International Commission on Radiological Protection ( ICRP 110 Male Female ), transport code Geant4 (version 10.3 ). calculated equivalent effective doses normalised simulated Kerma-Area Product (KAP), resulting in two conversion coefficients H T / KAP E . To properly evaluate risk exposure, several dose-dependent parameters have been investigated, namely: radiological (tube kilovoltage peak (kVp), type projection, field size (FOV)), operator positions. Four projections AP , PA LAO 25 ° RAO ) for three X-ray energy spectra 80 100 120 kVp) with four different values FOV 15 × cm 2 20 30 results showed that increase increasing tube voltage as well size. Recommended projection procedures, whenever possible, should be rather than projection. most critical main respectively. comparison our literature data good agreement allowing their use dosimetric characterization
