A CT –scanner is a large square or around X-ray machine with the tunnel through the center.

During your CT scan you will lie on the table that slowly passes through the tunnel. As you moved through the tunnel a joined ring called Gantry will rotate around your body. The Gantry contains a tube that will relise X-ray bims and detectors that will measure the amount of radiation absorbed by your body. The X-ray bims will capture many views of your body from different angles as the Gantry spins. The detectors will send data to the computer that will create cross-sectional images of the bones and soft tissues inside your body. The scann allows your doctor to see the location of a condition inside your body which will help them to decide how to treat it or to see how well your treatment is progressing.
