X-ray is an imaging technique that uses electromagnetic radiation to capture images of the inside of a body. An x-ray image shows solid and dense structures (like bones) in a white colour as the x-ray particles are less able to pass through them. The density of substances determines the shade in the image that an x-ray machine produces. Areas with air are shown in black and fluids are shown in shades of grey.

What is the x-ray process like?
Having an x-ray taken is a simple procedure that requires little preparation on the patient’s part. The procedure starts with you being given instructions on how to position yourself so that the radiologist can capture the required images. Depending on the area for which the x-ray is being taken, the patient may be asked to change positions several times. You could be standing, sitting or lying down and multiple images are captured until the radiologist gets an image of what is needed.
