'''Computed tomography''' (CT) is a diagnostic procedure that uses special X-ray equipment to create cross-sectional pictures of a person's body. CT images are produced using X-ray technology and powerful computers.
During a CT scan, the patient lies still on a table. The table slowly passes through the center of a large X-ray machine. The test is painless. During some tests, the patient recieves a contrast dye, which makes parts of their body show up better in the image.<ref>http://www.nlm.nih.gov/medlineplus/ctscans.html</ref>
