How does the CT scan work?

The CT scanner features a large ring which your body slowly passes through on a movable table. As you pass through the ring, the x-ray tube spins around you inside the scanner housing, producing a series of cross-sectional helical images. The data acquired while you are passing through the scanner is converted to “real time” pictures by the CT computer. To make a clearer picture of certain parts of your body, some CT scans require the use of contrast materials, which are substances that show up pure white on the x-ray image. Two types of contrast materials that will be administered orally and intravenously.
