What does the CT machine look like?
The CT scanner is a large machine with a wide hole in the center, something like a “doughnut”. Since the machine is only about a foot thick, only a small portion of your body will be inside the machine at any one time. The patient lies on a table, which can move up or down as well as slide into and out of the center of the hole. Within the machine, an x-ray tube on a rotating slip ring moves around the body to produce images, making clicking and whirring noises as the table moves.
