The program is heavily inspired by the use of x-ray imaging in medicine, but can also be used for simulating industrial and other applications.
ImaSim works in a modular approach; one assembles the x-ray source (using SpekCalc, co-developed by the same group), the subject to be imaged and the imaging panel, and then one defines the overall geometry. Image formation can then be simulated and various parameters can be changed. ImaSim was developed by Guillaume Landry, François deBlois and Frank Verhaegen at McGill University (Montreal, Canada) and Maastro Clinic (Maastricht, the Netherlands). ImaSim is brought to you by the same team that made the GUIs available for the codes SpekCalc (calculation of x-ray spectra) and RadSim (simulation of individual particle interactions). Inquiries regarding the software may be send using our contact form. The code is made available for Windows in 4 different ways: A light version, which only covers planar x-ray imaging and CT imaging and includes a selection of precalculated spectra and geometries (no option to edit spectra, or geometry). This version is made available for free, but has limited use.
Professional version for research by single users, available for a modest fee. This version covers planar x-ray imaging, CT imaging, portal imaging and cone beam CT imaging. Editors are available for photon spectra, object geometry and materials, imaging geometry and detector response. This version is intended for researchers and students.
ImaSim Academic, if you plan to use it with a group of students (more than one user). This option allows you to buy the number of licenses you need, including an academic discount. Also ONLY for non-commercial research and teaching purposes.
Users who intend to make use of ImaSim in a commercial setting, either to generate demonstration cases or to build the code in a commercial product, should please contact us to obtain a commercial license.
