X-ray Imaging

All x-ray imaging is based on the absorption of x rays as they pass through the different parts of a patient’s body. Depending on the amount absorbed in a particular tissue such as muscle or lung, a different amount of x rays will pass through and exit the body. The amount of x rays absorbed contributes to the radiation dose to the patient.¬†During conventional x-ray imaging, the exiting x rays interact with a detection device (x-ray film or other image receptors) and provide a 2-dimensional projection image of the tissues within the patient’s body – an x-ray produced “photograph” called a “radiograph.”

A standard X-Ray is painless. You cannot see or feel X-Rays. Everybody receives a small amount of radiation from the environment every day. The radiation received from any single X-Ray is very small, and would be similar to the amount you would be exposed to on a transatlantic flight.


Are there any risks?

Unborn children are at greater risk from being exposed to X-Rays because they are still developing. For this reason, routine X-Ray examinations may not be performed on women who could be pregnant or get pregnant within 28 days of a normal menstrual period. For some examinations that need higher doses of X-Ray, this may be reduced to 10 days. If you are or suspect that you may be pregnant, please tell the radiographer before the X-Ray is carried out. All the information you give will be treated with the strictest confidence.
