Monte Carlo simulations

Monte Carlo simulations are used to calculate energy deposition in reference human models as a function of particles type, energy and location. Particles can be located in any region of the model (source), where they are emitted isotropically. Monte Carlo simulations are performed for monoenergetic photons and electrons from 5 keV to 10 MeV (log scale). Energy deposits are recorded in every voxel and every region of the model (target), along with their estimated statistical uncertainties. Energy deposits are then converted in Specific Absorbed Fractions (SAFs), which are used to calculate S values.

simu

Producing a complete data set for one model (all sources, particle types and energies) requires ∼30 000 simulations, the equivalent of ∼750,000 CPU hours of computation. Monte Carlo simulations being "embarrassingly parallel", and thanks to the multiple computing resources of the OpenDose collaboration, the data for one model can be produced in a few months.

Production status

The data production status can be observed with the button below. It makes a query on the whole OpenDose database and displays how many simulations have been made for each model. By hovering the charts, the label shows the count (number of simulations) for a source - target couple.
