What is an x-ray?

X-rays are a form of electromagnetic Radiation like radio waves and visible light. The frequency and energy of x-rays is much greater than visible light. X-rays are produced in an x-ray tube and are able to pass through the body onto a detector to form a diagnostic image.

What happens during an x-ray?

When the X-rays pass through the body some are absorbed by the organs and structures of the body whilst others travel through to the detection equipment used to form the image. The images are formed by projection – images of structures in the path of the x-rays are projected onto the detector.

Depending on the part of the body being imaged, patients will either lie on a table or be positioned sitting or standing against the imaging equipment.

It is important to keep still while the x-ray is being taken in order to get a crisp image. For some examinations several projections are taken to fully demonstrate the anatomy being imaged. The examination usually takes between five and ten minutes.

The radiographer taking your x-ray will be able to see and hear you at all times.

You don’t usually need to make any preparations before an X-ray. However if you think you may be pregnant or have any concerns about the procedure, please make sure to contact our team.
