ELECTRON BEAM RADIATION SYSTEM WITH COLLISION DETECTION FUNCTIONALITY

The present invention relates to the field of electron beam machines, such as linear straight through machines, and methods used for therapeutic uses. More particularly, the present invention relates to electron beam machines that incorporate a rotary coupling system to easily attach and manually or automatically rotate field defining members such as applicators and/or shields to the electron beam machines. The rotary coupling systems also incorporate functionality to automatically detect collisions involving the electron beam machines such as between an electron beam machine and other equipment or a patient.
