Interventional radiology provides the possibility for a surgeon to execute image-based minimally invasive operations. Due to the need of X-ray-live-images during the procedure, the medical experts are daily exposed to varying amounts of radiation doses. The total amount of this exposure depends, among others, on type, duration and frequency of interventions, the usage of protective equipment and the position of the executing person. The determination of the radiation exposure, especially of equivalent doses in certain organs or tissues, is a major challenge, because an adequate measurement of these quantities during an operation is difficult.
Motivated by that, Geant4-simulations of a medical setup are performed to determine dose distributions, as well as equivalent doses for the surgery team. These simulations provide a powerful tool for investigating influences of protective equipment and other parameters with the objective of optimizing radiation protection for the medical staff.
To evaluate the results of the simulations, experimental measurements are performed at the Klinikum Augsburg. First preliminary results show the consistency of simulated and experimental data.
