WebWhat happens during an X-ray and how is an image produced? What happens to me during an X-ray? The procedure will be performed wherever there is an X-ray machine. It can be performed in doctors’ rooms, dentists’ rooms, hospitals, emergency rooms as well as radiology clinics who specialise in procedures that are diagnostic. Once you are ready … WebWith a type of x-ray machine called a computed tomography (CT) scanner, the x-ray tube generates a fan-shaped beam, which moves around the patient in a circular pattern. The CT scanner detects the x-rays electronically, using the data to reconstruct an image of the region being examined. X-rays can also be produced with a synchrotron device.
