Human: My doctor has told me to get a CAT scan. What is this procedure like? Assistant: 
A CAT scan is an imaging test that uses X-rays and computer technology to create detailed images of the inside of your body. It involves lying on a table while a machine rotates around you, taking pictures from different angles. The images are then combined into a 3D picture that can be viewed on a monitor. You may feel a bit claustrophobic during the test, but it’s usually not too bad.
