HOW CT SCANNERS WORK

A computerised tomography (CT) scan uses X-rays and a computer to create images of objects inside a body -  or in this case, a pot.

During a CT scan, the person or object is placed on its back on a flat bed.

The CT scanner consists of an X-ray tube that rotates around the object.

These rays are received by a detector on the opposite side, and an image is created.

Images produced by a CT scan are called tomograms and are more detailed than standard X-rays.

A CT scan, for example, can produce images of complex internal structures and shapes.

The technology has previously been used to scan the insides of Egyptian mummies.
