What is a computed tomography (CT) scan?

A CT scan (or computed tomography scan is a type of test that combines X-rays with a computer that produces many 3-dimensional (3D) images of the body part being scanned. A CT scan takes pictures of your bones, muscles, organs, and blood vessels. The “camera” looks like a big doughnut with a “bed” that lies in the “doughnut hole.” This bed will move in and out as pictures are being taken. The camera is inside the doughnut and spins around you as you lay on the bed, but does not touch you.
