X-ray of her bowels that required an enema containing barium given to her by the X-ray technician?

In some x-ray departments, the x-ray technician undergoes training to administer the barium enema to the patient without doctor supervision. A radiologist will evaluate the results and may participate in the patient's positioning so that the diagnosis is as accurate as possible. A barium enema is one of the most accurate ways of evaluating the large bowel.
