What is an X-ray?
An x-ray is produced when energy is given off following an interaction
between high-speed electrons and atoms of the receiving target anode.
X-rays are only produced at the time of exposure and are not constantly
occurring in the environment.
The technologist positions the patient using a light source and
a series of landmarks obtained by pressing various body parts to
find reference points.
You will have to hold your breath for a
few seconds for x-rays of the chest and abdomen area but this
is not necessary for x-rays of the arms, legs and head.
Although you may be required to hold awkward positions for a short
period of time, there is no discomfort from the x-ray exposure.
How Do I Prepare for an X-ray?
Plain x-rays of the chest, abdomen, arms, legs and spine require
no preparation and generally take only a few minutes to complete.
However, street clothes and jewellery must be removed from the
area of interest as they can interfere and cover the anatomy.
