An X-ray machine is a medical imaging device that produces images of the inside of the body using X-rays, a type of electromagnetic radiation. X-rays are able to penetrate through soft tissues, such as skin and muscle, but are absorbed by denser materials, such as bones and organs, producing a shadow image on photographic film or digital sensors. The X-ray machine typically consists of a tube that generates X-rays and a detector that captures the X-rays after they have passed through the body. The X-ray tube is positioned opposite the detector, with the part of the body being examined placed between the two. To produce an X-ray image, the patient must remain still during the procedure, as even slight movement can blur the image. The X-ray technician will typically position the patient and the machine to obtain the best possible image of the area of interest.
