 The Gaminite icon is an amazing machine. It has overcome several limitations of previous Gaminite generations, such as the inability to fractionate or use image guidance. It begins with the same automatic delivery system as the perfection which came before it, but then adds a combine CT imaging arm, an adapter for mask immobilization, an infrared camera for motion management based on a fiducial place on the patient's nose. Traditional frame-based treatment with the Gaminite is believed by many to have an uncertainty of less than one millimeter, which is an importantly recognized clinical threshold for radio surgery. But can the same be said for frameless treatment with the icon? We set out to find out, using various methods, to identify the individual uncertainty for each step in the workflow. Then we summed all the uncertainties with quadrature based on ICRU recommendations to give a total workflow uncertainty for frameless Gaminite treatment. And what we found bears significance on the choice of immobilization and or the use of setup margin for certain clinical scenarios.
