We have a combination of RN's and Rad techs. I work in Mass. and the Depart. of Public Health mandates that you have a rad tech (RT) to run the equipment. In fact by DPH standards only an MD. or RT can even turn on the equipment or move the table (and yes we are also filmless). We all rotate through the position of recording. Only RN circulate as we give meds. We just scrub to set up and then break scrub as our docs are adults and can manage to do the procedure. Our RT pans the table and moves the camera. Hope that helps. No CVT's.
