A method for determining a configuration setting of a source of ionizing radiation reducing a radiation dose absorbed by a patient and a practitioner in a medical operating room during a procedure. Prior to the procedure a database of maps of simulated propagation and scattering of ionizing radiation in a model of the medical operating room is obtained for different configuration settings. During the procedure, a position of the practitioner is determined. After determining a set of configuration settings of the source enabling the production of an image of a target anatomical structure a radiation dose absorbed by the patient and the practitioner is determined using the maps from the database. A recommended configuration setting for which a combined radiation dose is reduced is then outputted.

Method for determining a configuration setting of a source of ionizing radiation

A method for estimating a spatial distribution of the hazardousness of radiation doses for individuals evolving in a medical operating room defining a three-dimensional environment surrounding at least one source of radiation. First a three-dimensional model of the environment is obtained. Then a simulation of radiation doses attributable to ionizing radiation emitted from the source and scattered by the environment is computed in the model. Then, an image indicating the spatial distribution of the hazardousness for an individual of the radiation doses is generated and displayed. The three-dimensional model comprises models of individuals when the individuals are present in the environment and the image is a three-dimensional image generated for at least a portion of the model including said models of individuals.
