Gate currently supports simulations of Emission Tomography (Positron Emission Tomography - PET and Single Photon Emission Computed Tomography - SPECT), Computed Tomography (CT), Optical Imaging (Bioluminescence and Fluorescence) and Radiotherapy experiments. Using an easy-to-learn macro mechanism to configurate simple or highly sophisticated experimental settings, GATE now plays a key role in the design of new medical imaging devices, in the optimization of acquisition protocols and in the development and assessment of image reconstruction algorithms and correction techniques. It can also be used for dose calculation in radiation therapy, brachytherapy or any other application.

This snap contains Gate bundled with Geant4 (with QT, and all optional Geant4 datasets), ROOT, and PyTorch. Simply run Gate or Gate --qt on the command line to begin using it.

Snaps are sandboxed applications designed to be portable and run across a wide variety of Linux systems. Due to the sandboxing, please ensure all your work is contained within your $HOME folder to be accessible.

Please consider installing the root-framework snap in order to make root and other binaries also available on your system. This is not required to use the Gate snap, but may be desired by people who wish to use ROOT to analyse their output. Simply run sudo snap install root-framework or visit for more information.

This product includes software developed by Members of the Geant4 Collaboration ( )
