What is an X-ray?
X-rays are created by using an x-ray machine to pass a small amount of radiation a particular part of the body. As it passes through, the radiation is absorbed by the denser parts of the body and easily travels through less dense tissue. This image is captured on x-ray film placed on the other side of the body. The x-ray film, which looks like a photo negative, clearly indicates dark areas of less dense tissue and light areas of the most dense tissue, such as bone.
X-rays can help diagnose disease and injury to the body. Depending on which part of the body is being studied, an x-ray can take on different forms, with varying equipment and patient requirements. X-rays can be used to study the head, chest, digestive system, urinary system, as well as the bone and joints.
How it is performed
During an X-ray, a technologist carefully positions the part of your body being examined onto a special X-ray table. If necessary, the technologist may place a lead apron over certain other parts of your body to shield these parts from X-ray exposure. At this time, you will be asked to remain very still while the X-ray is focused onto the imaged area. The technician then steps behind a window while the image is being taken.
How to prepare
You should wear loose fitting clothing for the exam. The technologist might have you remove jewelry or other metallic objects from your body. Depending on the exam, you might be asked to change into a hospital gown.
