CT scan

A CT scan is performed using a special x-ray machine which produces a cross-sectional image (or slice) of the body.

The scanner consists of a ‘doughnut-shaped’ structure called a gantry which has a hole in the centre of approximately 75 cm in diameter, that you pass through while lying on a couch.

X-rays are produced from inside the gantry which rotates in a circle around you whilst you lay still. The x-ray beams pass through your body and are detected by electronic sensors on the other side of the gantry. This information is then passed to a computer which produces a picture of the internal structure of your body.
