The image, or x-ray film, is produced when a small amount of radiation passes through the body to expose sensitive film on the other side.
During conventional x-ray imaging, the exiting x-rays interact with a detection device (x-ray film) and provide a 2-dimensional projection image of the tissues within the patient's body. This produces the x-ray.
X-rays are very popular in general medicine and used predominantly for the imaging of bones and the chest area.
The chest x-ray is the most common radiologic examination. During this examination, an image of the heart, lungs and other anatomy is recorded on the film.
