Changing the way personal dosimetry is performed in nuclear medicine: switching from physical dosimeters to computational methods

The purpose of this study is to develop an automatic computer program to calculate the radiation received by the nuclear medicine staff. This tool will provide a fast and accurate dosimetry service which will be capable of showing doses received in real time. The program will allow to check dose constraints for every worker monitored and show possible contamination zones. Second by second Monte Carlo Simulations will run to assess radiation received using 3D reconstructions of the whole work area. These simulations will be accelerated using GPU computing and artificial intelligence algorithms. Computer vision algorithms will provide a reliable positional tracking for the staff and the radiation source. This will be used to create a 3D reconstruction of the whole work area considering the exact posture and position of the workers monitored and of the shielding equipment used. An emphasis on the accuracy for tracking of the hands will be made, because occupational exposure may lead to high finger doses which can surpass the legal dose limit. Augmented reality glasses will be used to provide real time results of the simulation. The staff will be able to use these glasses to check the skin dose as colored map distribution over their hands.
