    Abstract:

    To perform accurate dosimetric studies for internal radiotherapy and contamination, a new tool (Oedipe) was developed for personalised voxel-based dosimetry. Patient-specific geometries are created from anatomical images and associated with the Monte Carlo N-Particle eXtended code, MCNPX, using the Graphical User Interface Oedipe. Computer time (CPU) is a limiting factor to use routinely Oedipe for nuclear medicine, particularly for dosimetric calculations at the tissue level. The Los Alamos National Laboratory developed the new version 2.5e of the MCNPX code in order to reduce CPU time. The presented studies were performed to evaluate the CPU time decrease using MCNPX2.5e in the context of personalised voxel-based dosimetry. Results show that the optimisation is well suited for internal dosimetry and involves an important CPU time reduction by a factor equal or higher to 100.
