Human: My doctor wants me to have a CT scan. What is the procedure like? Assistant: 
The procedure for a CT scan is relatively simple and painless. You will be asked to lie on a table while a technician moves an X-ray machine around your body. The machine takes pictures of the inside of your body, which are then sent to a computer that produces cross-sectional images of your organs and tissues. These images are viewed by your doctor, who can use them to diagnose any medical conditions or illnesses.
