Monte Carlo simulation of patient organ doses in interventional radiology procedures

Medical procedures using ionising radiation constitute by far the largest contribution to people by man-made radiation sources. Although the benefit for the patients exposed will normally outweigh the risk associated with the radiation, tissue reactions have been reported for patients undergoing fluoroscopically guided procedures (Balter et al, 2010). In this context, WG12 of the European Radiation Dosimetry Group EURADOS (a network of 80 European institutions and more than 600 members) carries out research projects and coordinated activities within the field of area dosimetry. A specific task group (https://eurados.sckcen.be/en/working-groups/wg12- dosimetry-medical-imaging/wg12-task- groupsanchor-wg12-sg2-patient-dosimetry) was set up to estimate organ doses in interventional radiology. The main purpose is to characterize the variability of measurements and calculations depending on the dierent parameters that can aect the dose reconstruction (DICOM RDSR data, manufacturers, dosimetry tools, . . . ). Results of dierent Monte Carlo codes (MCNP6, MCNPX, GATE/Geant4, PHITS, PyMCGPU-IR) will be compared in several test cases. Among the 20 participants, UPC’s research group is already participating with the dose calculation by using PyMCGPU-IR. This master thesis will allow to also participate with PENELOPE/penEasy.
