View Full Version : Patient Collision Forces in Medical Exams

One hazard in the use of large medical x-ray systems is the possiblity of
collision between components of these systems and the patient or user. In
developing a "collision detection system," I seek information on the
acceptable collision forces that can be applied to a patient in such a
situation. I'm also seeking information on currently accepted practices
with regard to this issue. Some system use a "software envelope" while
others use force sensors. What is the "state of art?"

I am attempting to separate acceleration/decelleration forces from
collision forces using some type of matched digital filter. Any
commentary or pointers to information sources that readers can provide
would be appreciated.
