Projects / GATE


GATE is a software package dedicated to numerical simulations in medical imaging and radiotherapy. It supports simulations of Emission Tomography (Positron Emission Tomography (PET) and Single Photon Emission Computed Tomography (SPECT)), Computed Tomography (CT), and Radiotherapy experiments. It makes it easy to use existing Monte Carlo simulation packages according to the requirements of a simulation. It allows accurate description of time-dependent phenomena such as source or detector movement and source decay kinetics. It includes well-validated physics models, geometry modeling tools accommodating complex scanner geometries, models for detector electronic response, and efficient visualization utilities. Modelling of CT scans and calculation of dose can also be performed.
