X-ray Simulation Platform for Explosive Detection Equipment

This proposed effort will develop the Particle/Ray Interaction Simulation Manager (PRISM) software platform which was begun as a Phase I program. The goal of PRISM is to meet the x-ray simulation needs of the explosive detection community. In Phase I a user survey was conducted of a wide range of system manufacturers who reported that existing simulation tools do not meet their desired needs for ease-of-use, run time, or modelling of complex objects. Therefor we are designing PRISM to leverage these existing tools, while adding an easy-to-use graphical interface for specifying system parameters and visualizing models. In this way PRISM will create a unified user-interface wrapper for commonly used simulation tools, which we hope will be of high value to the user community. PRISM will have the following key features: (1) User interfaces for both expert and non-expert users, (2) Open-source architecture that can be linked to numerous simulation tools, (3) Input from CAD files so that complicated objects can be easily modeled, (4) A digital luggage and cargo library tested with experimental data. The final deliverable will be a functional, commercial-grade, open-source, PRISM platform, which will provide an easy-to-use interface for defining simulation structures. PRISM will initially be fully integrated with GEANT4, but will be architected for future expansion to other simulation tools. As part of the commercialization plan, Triple Ring will provide customization services and additional library models.
