X-rays are used by those in the medical field to peer into a person's body without making any incisions or any invasive techniques. When doctors need someone x-rayed they normally send the patient to an x-ray lab. All x-ray labs have x-ray machines that use x-rays and x-ray photography to looking inside people. Some x-ray labs specialize in veterinary x-rays. Some x-ray labs also have magnetic resonance imaging machines or MRI machines. Some x-ray labs also have computed axial tomography machines, which are sometimes called CAT scan machines or CT scan machines. Most hospitals have x-ray labs on site. Few doctors' offices have x-ray machines so physicians frequently utilize the services of independent x-ray labs. Some x-ray laboratories specialize in taking dental x rays. Dental x rays help dentists diagnose problems people have with their teeth. Dental x ray labs are also utilized by orthodontists and oral surgeons.
