CT scan stands for Computed Tomography scan. This scan takes a series of X-rays and uses a computer to put them together. This scan is painless. The CT machine takes pictures of ones body from different angles and gives a series of cross sections(slices) through the part of the body being scanned. This CT scan can produce a very detailed picture of the inside of the body. A CT scan is used to define normal and abnormal structures in the body and/or assist in procedures by helping to accurately guide the placement of instruments or treatments.
A CT scanning machine is large and shaped like a doughnut. There is a couch that you lie on. The couch can slowly slide backwards and forwards through the hole of the doughnut. The pictures are taken as you move through the machine. The scan takes about 10 to 15 minutes.
