Abstract
For radiation safety, a fluoroscope has an adjustable X-ray source-to-intensifier distance (SID) and an X-ray transparent spacer positioned between the source and receptor. As a distance between the source and the intensifier is changed, the spacer is moved or a different sized transparent spacer is used, to ensure a safe minimum skin-to-source distance (SSD) is maintained. A processor is programmed to inhibit the generation of X-rays if the SID is greater than a defined distance and the spacer is not in position.
