My Spine Explained
Figure 15.1
This is a picture of a CT scan machine.
The large square part in the back with the round opening is where the X-rays
are generated around the patient. This is called the gantry and can be
inclined at angles to allow for better visualisation of the tissues of the body.
Modern scanners are called spiral CT scan machines and can currently take
many images at a time. The table moves with an electric motor and allows the
X-rays to pass over different tissues of the body as the patient passes through
the gantry. CT scan machines generate a large amount of radiation and a CT
scan should therefore only be performed for specific clinical indications.
