I work in a lab that the other techs scan from the side. It was not a problem for me and I don't have to rearrange the room. My paitients just lie with the head at the other end for Carotids and I pull the machine down. For my Arterials, the patient has the head at the other end and the machine is pushed up to that position. I have gotten comments from previous patients that they prefer my scanning to the other for the simple reason I am not stretching my arm across thier body and face to scan.
