Digital X-ray involve exposing a body part to a small dose of radiation to produce an image of an internal organ. An X-ray image is produced when a small amount of radiation passes through the body and strikes an image sensitive plate placed on the other side of the body. This film is then placed in a developing machine to produce images.
What To Expect
A technologist positions you on the exam table and places a film holder under the table in the area of the body to be imaged. Pillows may be used to help you hold the proper position. Then the technologist steps behind a radiation barrier and asks you to hold very still, without breathing for a few seconds. The x-ray equipment is activated, sending a beam of x-rays through the body to expose the film. The technologist then repositions you for another view, and the process is repeated as necessary. The entire exam usually takes about 5 – 30 minutes.
When your x-rays are completed you will be asked to wait until the technologist checks the images. Occasionally, additional views are needed for a more detailed look at a questionable abnormality.
Preparation and Precautions
No special preparation is required for most bone x-rays. You may be asked to change into a gown before your examination and remove jewelry, eyeglasses and any metal objects during the exam.
