X-rays are ideal for looking for fractures in bone and imaging certain soft tissues. You are positioned on or against a special table or surface so that the part of your body being imaged lies between the image receptor (either an X-ray detector plate or photographic film) and the X-ray source. After positioning the X-ray machine, the radiographer stands behind a screen. You are exposed to X-rays for a fraction of a second, and the whole procedure takes only a few minutes.
