IMF™ & GMF

Isocentric Mounting Fixtures

IMF and GMF are measurement device mounting fixtures for measurement of linear accelerator beams at any gantry angle. The systems provide secure device mounting, electron cone compatibility, and buildup based on configuration.



Features & Benefits

  • QA measurements at isocenter for any gantry angle
    • Output, symmetry, flatness, field size, penumbra, beam center, and more, depending on device used
    • Determine gravity-induced effects on dose constancy, symmetry, flatness, MLC, jaws and more
    • Reproducible measurement device setup
    • Accommodates additional buildup material
